Abstract
Description
Technical Field
[0001] This application relates to the field of skin care technology, specifically to a skin care device and care system. Background Technology
[0002] Currently, the light emitted by the light-emitting components of skin care devices (such as hair removal devices) needs to pass through a light guide unit before exiting through the light outlet to the outside. However, the numerous internal components of hair removal devices limit the area of the light outlet corresponding to the light guide unit at the light outlet, resulting in a smaller area removed per session and affecting the hair removal efficiency. Utility Model Content
[0003] In view of the above problems, this application provides a skin care device and care system.
[0004] The skin care device according to this application includes a housing, a light-emitting component, and a heat dissipation component. The housing has a light-emitting port. The light-emitting component is housed inside the housing. The light-emitting component includes a light-emitting unit and a light-guiding unit. The light-emitting unit emits light, and the light-guiding unit is disposed in the light path of the light-emitting unit, guiding the light emitted by the light-emitting unit to the light-emitting port and outwards to the outside of the skin care device. The heat dissipation component includes a thermoelectric cooling unit and a heat-conducting unit. The heat-conducting unit includes a first heat-conducting element, which connects the light-guiding unit and the thermoelectric cooling unit. The first heat-conducting element absorbs heat from the light-guiding unit and transfers it to the cold end of the thermoelectric cooling unit. In a plane perpendicular to the thickness direction of the skin care device, the projections of the thermoelectric cooling unit and the light-guiding unit are at least partially offset.
[0005] In the skin care device of this application, the cold end and the light guide unit are bonded together via a first heat-conducting element. Therefore, the thermoelectric cooling unit and the light guide unit do not need to be installed as a whole inside the housing. The thermoelectric cooling unit and the light guide unit can be arranged independently. The position and size of the thermoelectric cooling unit will not interfere with the position of the light guide unit and the light outlet, nor will it limit the size of the light outlet. The light outlet can be further enlarged to improve hair removal efficiency. The projection of the thermoelectric cooling unit toward the light guide unit is at least partially offset from the light guide unit. The offset portion can be used to increase the volume of the light guide unit and the area of its corresponding light outlet, thereby increasing the area of hair removal per session. The offset portion can also be used to reduce the size of the housing at the corresponding position, making it easier to narrow the housing at the light outlet and improve aesthetics.
[0006] In some embodiments, the distance between the projection of the thermoelectric cooling unit and the projection of the light guide unit in a plane perpendicular to the thickness direction of the skin care device can further increase the space between the projection of the thermoelectric cooling unit toward the light guide unit and the light guide unit. The thermoelectric cooling unit does not occupy the space on one side of the housing where the light guide unit is located, which is beneficial for making the light guide unit larger.
[0007] In some embodiments, the heat dissipation assembly further includes an exhaust unit, the housing is further provided with an air outlet, and the skin care device further includes a bracket. The bracket is disposed inside the housing, and the exhaust unit and the light-emitting component are both located on the bracket. The bracket forms a heat dissipation channel, one end of which is connected to the exhaust port of the exhaust unit, and the other end is connected to the air outlet. The light-emitting component is located on the heat dissipation channel.
[0008] After the airflow passes through the first air inlet into the exhaust unit, the exhaust unit blows the airflow out through the exhaust port. One end of the heat dissipation channel is connected to the exhaust port of the exhaust unit, so the airflow, after being discharged from the exhaust unit, can directly flow into the channel and be discharged to the outside of the housing through the exhaust port. The light-emitting component is located on the channel, and the airflow passing through the channel can carry away the heat of the light-emitting component to dissipate heat.
[0009] In some embodiments, the bracket includes a base and a top cover. The base has a first zone and a second zone, with the exhaust unit located in the first zone and the heat dissipation channel, the light-emitting component, and the heat dissipation component all located in the second zone. The top cover is disposed in the second zone and is connected to the housing and / or the base, with the thermoelectric cooling unit supported on the top cover.
[0010] During airflow, the top cover and the base serve as the two sidewalls of the heat dissipation channel. On the one hand, they can guide the direction of airflow into the heat dissipation channel, and on the other hand, they can restrict the airflow from the direction perpendicular to the extension of the top cover and the direction perpendicular to the extension of the base. In other words, the top cover and the base can restrict the airflow from dispersing within the heat dissipation channel, which helps to gather the airflow in the heat dissipation channel, increase the airflow velocity, thereby improving the heat dissipation efficiency and ensuring that the heat generated by the light-emitting component can be carried away.
[0011] In some embodiments, the top cover includes a first side and a second side facing away from each other, the thermoelectric cooling unit is disposed on the first side, the light guiding unit is disposed on the second side, and the first heat-conducting element is located between the thermoelectric cooling unit and the light guiding unit respectively.
[0012] The top cover provides support for the thermoelectric cooling unit, preventing it from shifting during use and improving its stability. The first heat-conducting element absorbs heat from the light-emitting component and conducts it to the cold end via thermal conductivity.
[0013] In some embodiments, the upper cover is provided with a through groove penetrating the first side and the second side. The first heat-conducting element includes a first heat-conducting part, a second heat-conducting part, and a third heat-conducting part connected to the first heat-conducting part and the second heat-conducting part. The first heat-conducting part is located on the first side and connected to the thermoelectric cooling unit. The second heat-conducting part is located on the second side and connected to the light-guiding unit. The third heat-conducting part passes through the through groove.
[0014] The through slot can shorten the length of the first heat-conducting element, thereby shortening the heat conduction path length between the thermoelectric refrigeration unit and the heat-conducting unit, thus improving the heat conduction efficiency.
[0015] In some embodiments, the upper cover is further provided with an upper cover extension wall, which is located on the first side and extends protruding from the second side toward the first side, and the exhaust unit and the thermoelectric cooling unit are respectively located on opposite sides of the upper cover extension wall.
[0016] The extended wall of the top cover can isolate the exhaust unit, preventing the airflow that has been blown out by the exhaust unit and has already undergone heat exchange from blowing onto the thermoelectric cooling unit, thereby ensuring the cooling effect of the thermoelectric cooling unit.
[0017] In some embodiments, the base is provided with a receiving groove, and the light-emitting unit is at least partially housed in the receiving groove. The receiving groove can, on the one hand, increase the space for airflow in the heat dissipation channel, thereby increasing the flow area of airflow in the heat dissipation channel and enhancing the heat dissipation effect on the light-emitting component; on the other hand, it can increase the space inside the housing in the third direction, thereby accommodating a larger light-emitting unit in the third direction, thereby improving hair removal efficiency.
[0018] In some embodiments, the heat dissipation assembly further includes a heat dissipation unit connected to the hot end of the thermoelectric cooling unit. The thermoelectric cooling unit absorbs heat generated by the light-emitting component through the first thermally conductive element and transfers it to the heat dissipation unit. The heat dissipation unit absorbs heat from the thermoelectric cooling unit and conducts it to its surface via thermal conduction. The surface of the heat dissipation unit has a certain contact area with the air. When the airflow from the exhaust port passes over the surface of the heat dissipation unit, the airflow absorbs and carries away the heat from the heat dissipation unit.
[0019] In some embodiments, the projection of the heat dissipation unit onto the base at least partially covers the second area and serves to form the heat dissipation duct. The large coverage area of the projection of the heat dissipation unit at least covering the second area improves the heat dissipation effect.
[0020] In some embodiments, in the direction from the thermoelectric cooling unit to the heat dissipation unit, the heat dissipation unit includes a first surface and a second surface facing away from each other, with the first surface closer to the thermoelectric cooling unit than the second surface; the heat-conducting unit includes a second heat-conducting element located between the hot end of the thermoelectric cooling unit and the first surface, and used to absorb heat from the thermoelectric cooling unit and transfer it to the heat dissipation unit. The second heat-conducting element, located between the hot end of the thermoelectric cooling unit and the first surface, enhances the heat transfer efficiency between the hot end and the heat dissipation unit.
[0021] In some embodiments, in the direction from the thermoelectric cooling unit to the heat dissipation unit, the heat dissipation unit includes a first surface and a second surface facing away from each other, with the first surface closer to the thermoelectric cooling unit than the second surface; the heat conduction unit includes a third heat conduction element located between the housing and the second surface, the third heat conduction element absorbing heat from the heat dissipation unit and transferring it to the housing. The third heat conduction element, located between the housing and the second surface, enhances the diffusion rate of heat within the heat dissipation unit, thereby improving the heat conduction efficiency between the housing and the second surface.
[0022] In some embodiments, the base includes a seat and a first extension wall disposed on the seat. The first extension wall extends from the seat along the thickness direction of the skin care device and serves as a sidewall of the heat dissipation channel. The exhaust unit and the light-emitting component are located on opposite sides of the first extension wall, and the air outlet and the light-emitting component are located on the same side of the first extension wall. The first extension wall has an air inlet, which communicates with the exhaust port of the exhaust unit. The opposite ends of the heat dissipation channel are respectively connected to the air inlet and the air outlet. Since the air inlet on the first extension wall communicates with the exhaust port of the exhaust unit, and the opposite ends of the heat dissipation channel are respectively connected to the air inlet and the air outlet, the airflow discharged from the exhaust port of the exhaust unit can enter the heat dissipation channel through the air inlet, carrying away the heat generated by the light-emitting component located on the heat dissipation channel before being blown out from the air outlet, thus completing the heat dissipation of the light-emitting component. During the airflow process, the first extension wall, as a sidewall of the heat dissipation channel, can guide the flow of air entering the heat dissipation channel and prevent airflow from flowing back to the exhaust unit.
[0023] This application also provides a care system. The care system includes the skin care device described in any of the above embodiments. The cold end of the skin care device in the care system is attached to the light guide unit via a first heat-conducting element. Therefore, the thermoelectric cooling unit and the light guide unit do not need to be installed as a whole inside the housing; they can be arranged separately. The position and size of the thermoelectric cooling unit will not interfere with the position of the light guide unit and the light outlet, nor will it limit the size of the light outlet. The light outlet can be further enlarged to improve hair removal efficiency. The projection of the thermoelectric cooling unit toward the light guide unit is at least partially offset from the light guide unit. This offset portion can be used to increase the volume of the light guide unit and the area of its corresponding light outlet, increasing the area of hair removal per session. The offset portion can also be used to reduce the size of the housing at the corresponding position, facilitating a narrowing of the housing at the light outlet and improving aesthetics.
[0024] In some embodiments, the care system further includes a charging component for charging the skin care device.
[0025] The charging component can connect to and charge the skin care device. The skin care device may have one or more charging ports to adapt the system to various charging methods, thereby improving its versatility. In some alternative embodiments, the skin care device may also include a wireless charging module, allowing the charging component to power or charge the skin care device wirelessly, thus enhancing its ease of use.
[0026] In some embodiments, the care system further includes a controller that is communicatively connected to the heat dissipation assembly and the light-emitting assembly. The controller is disposed within the housing of the skin care device or is separate from the skin care device.
[0027] When the controller and skin care device are separate components, they communicate with each other via wired or wireless means. Wireless connection methods include, but are not limited to, Bluetooth and local area network (LAN) communication.
[0028] In some embodiments, the care system further includes a sterilization base. The sterilization base is used to hold the skin care device. The sterilization base provides stable support for the skin care device to prevent it from tipping over or being moved, and also sterilizes the skin care device.
[0029] In some embodiments, the care system further includes an adapter head. The housing has a light outlet, and the adapter head is detachably connected to the light outlet and used to modulate the light emitted from the light outlet to the outside, so that the modulated light is suitable for the care needs of different skin locations.

[0042] Please see Figure 1 This application describes a hair removal device using a skin care device 100. The skin care device 100 emits specific light to non-damage the normal epidermis. The light penetrates the skin and reaches the hair follicle root. The melanin in the hair shaft and follicle absorbs and converts this light into heat energy, thereby raising the temperature of the hair follicle. When the temperature rises sufficiently, the hair follicle structure undergoes irreversible damage. The damaged hair and follicle are removed through a natural physiological process, while surrounding tissues remain undamaged, thus achieving painless hair removal. The hair removal device described in this application can be an intense pulsed light (IPL) hair removal device, also known as a photon hair removal device. Of course, other types of hair removal devices can also be used; this application does not limit the specific type of hair removal device.
[0043] In this application, the length direction of the skin care device 100 is taken as the first direction X, the width direction as the second direction Y, and the thickness direction as the third direction Z.
[0044] Please see Figure 1 and Figure 2 The skin care device 100 includes a housing 10, a light-emitting component 30, and a heat dissipation component 50. The housing 10 has a light-emitting port 11. The light-emitting component 30 is housed inside the housing 10. The light-emitting component 30 includes a light-emitting unit 31 and a light-guiding unit 33. The light-emitting unit 31 emits light, and the light-guiding unit 33 is disposed in the light path of the light-emitting unit 31. The light-guiding unit 33 guides the light emitted by the light-emitting unit 31 to the light-emitting port 11 and emits it to the outside of the skin care device 100. The heat dissipation component 50 includes a thermoelectric cooling unit 52 and a heat-conducting unit 55. The heat-conducting unit 55 includes a first heat-conducting element 551. The first heat-conducting element 551 connects the light-guiding unit 33 and the thermoelectric cooling unit 52. The first heat-conducting element 551 absorbs the heat of the light-guiding unit 33 and transfers it to the cold end 523 of the thermoelectric cooling unit 52. In a plane perpendicular to the thickness direction Z of the skin care device 100, the projection of the thermoelectric cooling unit 52 and the projection of the light-guiding unit 33 are at least partially offset.
[0045] Specifically, the housing 10 is a structure used to mount other components of the skin care device 100 and to house these components within the housing 10. It serves to protect components such as the light-emitting component 30 and the heat-dissipating component 50. The cross-sectional shape of the housing 10 can be, but is not limited to, circular, elliptical, rectangular, or other polygonal shapes. The material of the housing 10 can be plastic or metal. When the housing 10 is made of plastic, it has good insulation properties, low cost, and light weight. When the housing 10 is made of metal, it has high strength, good wear resistance, and a long service life. The housing 10 has a light-emitting port 11. When using the skin care device 100, the user directly holds the housing 10 and aligns the light-emitting port 11 with the skin for hair removal.
[0046] The light-emitting component 30 is disposed inside the housing 10 and is used to emit specific light to the outside of the housing 10. The light-emitting component 30 includes a light-emitting unit 31 and a light-guiding unit 33. The light-emitting unit 31 is used to emit light, which is used to remove hair from human skin. The light-guiding unit 33 is disposed in the light path and is used to change the light path to guide the light to the light outlet 11 and out of the housing 10, thereby achieving hair removal. In this application, the light-guiding unit 33 is made of sapphire. In other embodiments of this application, the light-guiding unit 33 may be made of other materials. The light-emitting unit 31 generates a large amount of heat during use. Sapphire has high thermal conductivity and can quickly conduct the heat of the light-emitting unit 31 to the heat dissipation component 50, thereby reducing the skin temperature and reducing discomfort and potential skin damage during the hair removal process.
[0047] The heat dissipation assembly 50 is used to dissipate heat from the components inside the housing 10. The heat dissipation assembly 50 includes a thermoelectric cooling unit 52 and a heat conduction unit 55. The thermoelectric cooling unit 52 includes a cold end 523 and a hot end 521. The cold end 523 can absorb heat from the light guide unit 33 and transfer it to the hot end 521, thereby cooling the light guide unit 33. The cooling of the light guide unit 33 by the cold end 523 can be direct or indirect.
[0048] Traditional solutions employ direct cooling, where the cold end 523 is directly attached to the light guide unit 33 to absorb and cool its heat. If the cold end 523 is directly attached to the light guide unit 33, the thermoelectric cooling unit 52 and the light guide unit 33 need to be installed as a single unit inside the housing 10 and arranged as a whole. The light guide unit 33 is typically positioned opposite the light outlet 11 to cool the light and guide it to the outlet. In other words, the position of the light guide unit 33 within the housing 10 is related to the position of the light outlet 11. The size of the light outlet 11 is also related to the size of the light guide unit 33. It is understandable that a larger light outlet 11 and a larger light guide unit 33 result in a larger light coverage area and higher hair removal efficiency. However, the position and size of the thermoelectric cooling unit 52 are not related to the light outlet 11. Therefore, if the thermoelectric cooling unit 52 and the light guide unit 33 are always arranged as a whole, the position and size of the thermoelectric cooling unit 52 will interfere with the position of the light guide unit 33 and the light outlet 11, and limit the size of the light outlet 11, resulting in the hair removal efficiency not being improved.
[0049] Therefore, this application employs indirect cooling. Specifically, a first heat-conducting element 551 is provided between the cold end 523 and the light guide unit 33 to transfer heat between them. Thus, the cold end 523 is not in contact with the light guide unit 33, and the thermoelectric cooling unit 52 and the light guide unit 33 do not need to be installed as a whole inside the housing 10; they can be arranged independently. Furthermore, the position and size of the thermoelectric cooling unit 52 do not interfere with the position of the light guide unit 33 and the light outlet 11, nor do they limit the size of the light outlet 11. The light outlet 11 can be further enlarged to improve hair removal efficiency. Furthermore, the projection of the thermoelectric cooling unit 52 onto the light guide unit 33 is at least partially offset from the light guide unit 33, meaning that the thermoelectric cooling unit 52 is at least partially not in contact with the light guide unit 33. For example, in this application, the thermoelectric cooling unit 52 and the light outlet 11 are located on opposite sides of the light guide unit 33 in the first direction X. The thermoelectric cooling unit 52 is far away from the light outlet 11 in the first direction X, which can provide a certain amount of space for the light guide unit 33 and the light outlet 11. The light guide unit 33 can be further enlarged at least at the end near the light outlet 11 in the first direction X. Correspondingly, the light outlet 11 can also be further enlarged, thereby increasing the area of hair removal in a single session and improving hair removal efficiency.
[0050] The first heat-conducting element 551 can be one or more; in this application, there is only one. The first heat-conducting element 551 absorbs heat from the light-emitting component 30 and conducts it to the cold end 523 via thermal conduction. The shape and size of the first heat-conducting element 551 are not limited in this application. Furthermore, the first heat-conducting element 551 is made of a compressible thermally conductive material, including but not limited to fluorinated graphene aerogel, compressible thermal films, and thermal gap filling materials. The compressible thermally conductive material has a certain deformation space, and during installation, the first heat-conducting element 551 can be compacted to connect the thermoelectric cooling unit 52 and the light-guiding unit 33 respectively. Therefore, the first heat-conducting element 551 can better fit with the thermoelectric cooling unit 52 and the light-guiding unit 33, improving thermal conductivity.
[0051] In the skin care device 100 of this application, the projection of the thermoelectric cooling unit 52 toward the light guide unit 33 is at least partially offset from the light guide unit 33. The offset portion can be used to increase the volume of the light guide unit 33 and the area of its corresponding light outlet 11, thereby increasing the area of hair removal per session. The offset portion can also be used to reduce the size of the housing 10 at the corresponding position, making it easier to narrow the housing 10 at the light outlet 11 and improve the aesthetics.
[0052] Please see Figure 3 In some embodiments, the projection of the thermoelectric cooling unit 52 and the projection of the light guide unit 33 are spaced apart in a plane perpendicular to the thickness direction Z of the skin care device 100.
[0053] Furthermore, in embodiments where the projection of the thermoelectric cooling unit 52 toward the light guide unit 33 is at least partially offset from the light guide unit 33, the projection of the thermoelectric cooling unit 52 toward the light guide unit 33 can be completely offset, that is, the projection of the thermoelectric cooling unit 52 toward the light guide unit 33 and the light guide unit 33 are spaced apart. Exemplarily, the thermoelectric cooling unit 52 and the light guide unit 33 are arranged opposite each other in the third direction Z. Further, on the XY projection plane, XZ projection plane, and YZ projection plane, the projections of the thermoelectric cooling unit 52 and the light guide unit 33 are all spaced apart. Thus, the thermoelectric cooling unit 52 and the light guide unit 33 are completely offset, and the thermoelectric cooling unit 52 does not occupy the space on one side of the housing 10 where the light guide unit 33 is located, which is beneficial for increasing the size of the light guide unit 33 and the light outlet 11.
[0054] Please see Figure 2 and Figure 3In some embodiments, the heat dissipation assembly 50 further includes an exhaust unit 51, the housing 10 is also provided with an air outlet 15, and the skin care device 100 further includes a bracket 70. The bracket 70 is disposed inside the housing 10, and the exhaust unit 51 and the light-emitting component 30 are both located on the bracket 70. The bracket 70 forms a heat dissipation channel 80, one end of which is connected to the exhaust port 511 of the exhaust unit 51, and the other end is connected to the air outlet 15. The light-emitting component 30 is located on the heat dissipation channel 80.
[0055] Specifically, the exhaust unit 51 is used to draw in airflow from outside the housing 10 and guide it into the housing 10, thereby dissipating heat from the components inside the housing 10. Further, the exhaust unit 51 of this application is an axial fan. The air inlet 13 and air outlet 15 of the axial fan are not in the same direction, meaning the air duct of the axial fan itself can be flexibly configured to guide airflow into and out of the axial fan from different directions. The axial fan of this application draws in airflow in the third direction Z and blows out airflow in the second direction Y, which facilitates flexible layout of the axial fan inside the housing 10. After the exhaust unit 51 draws in airflow from outside the housing 10 through the gap and the first inlet and guides it into the housing 10, it blows the airflow out of the housing 10 at a certain pressure and speed. The airflow flows within the housing 10 at a certain pressure and speed, continuously absorbing and carrying away the heat generated by the internal components during its flow. The airflow carrying heat is discharged to the external environment through the air outlet 15, thereby reducing the internal temperature of the housing 10.
[0056] An air outlet 15 penetrates the housing 10, connecting the outside and inside of the housing 10. An exhaust unit 51 inside the housing 10 draws airflow from the outside and blows it into the housing 10. This airflow carries away heat from the internal components and flows out through the air outlet 15 to the outside of the housing 10, thus cooling the skin care device 100. There can be one or more air outlets 15; in this application, there are multiple air outlets 15. The air outlet 15 can be located anywhere on the housing 10 except for the light outlet 11. For example, the air outlet 15 is located on the side wall of the housing 10. The shape of the projection of the air outlet 15 onto the housing 10 includes, but is not limited to, a perfect circle, an ellipse, or a polygon. In this application, the air outlet 15 is projected as an ellipse. An ellipse has no sharp corners, making it less prone to accumulating dirt and preventing dust carried by external airflow from depositing on the side wall of the air outlet 15.
[0057] The bracket 70 is installed inside the housing 10 and is used to fix and install the exhaust unit 51 and the light-emitting component 30. The bracket 70 can be made of plastic or metal. When the bracket 70 is made of plastic, it has good insulation performance, low cost, and light weight. When the bracket 70 is made of metal, it has high strength, good wear resistance, and long service life. After the airflow passes through the first air inlet 13 into the exhaust unit 51, the exhaust unit 51 blows the airflow out from the exhaust port 511. One end of the heat dissipation channel 80 is connected to the exhaust port 511 of the exhaust unit 51, so the airflow can directly flow into the heat dissipation channel 80 after being discharged from the exhaust unit 51 and is discharged to the outside of the housing 10 from the air outlet 15. The light-emitting component 30 is located on the heat dissipation channel 80. The airflow passing through the heat dissipation channel 80 can carry away the heat of the light-emitting component 30 to dissipate heat from the light-emitting component 30.
[0058] Please see Figure 2 and Figure 4 In some embodiments, the bracket 70 includes a base 71 and a top cover 73. The base 71 has a first zone 701 and a second zone 702. The exhaust unit 51 is located in the first zone 701, and the heat dissipation channel 80, the light-emitting component 30, and the heat dissipation component 50 are all located in the second zone 702. The top cover 73 is disposed in the second zone 702 and is connected to the housing 10 and / or the base 71. The thermoelectric cooling unit 52 is supported on the top cover 73.
[0059] Specifically, both the exhaust unit 51 and the light-emitting component 30 are mounted on the base 71. The base 71 can bear part of the weight, preventing the exhaust unit 51 and the light-emitting component 30 from directly compressing the housing 10. The base 71 is made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, when the base 71 is made of plastic, it has good insulation performance, low cost, and light weight. When the base 71 is made of metals such as aluminum alloy, the housing 10 has high strength, good wear resistance, and a long service life.
[0060] The top cover 73 is a structure in the bracket 70 that can cooperate with the base 71 to confine the light-emitting component 30. The material of the top cover 73 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the top cover 73 is made of plastic, which makes the bracket 70 lighter and easier for users to carry. It is understood that the material of the top cover 73 and the base 71 can be the same or different. The top cover 73 can be connected to the housing 10, the base 71, or both.
[0061] The base 71 has a first region 701 and a second region 702. In the first direction X, the first region 701 is further away from the light outlet 11 than the second region 702. The upper cover 73 is disposed in the second region 702, and in the third direction Z, the light-emitting component 30 is located between the upper cover 73 and the base 71. In one example, the upper cover 73 and the base 71 are closed in the third direction Z. Thus, the upper cover 73 and the base 71 can block at least part of the light emitted by the light-emitting component 30 in the third direction Z, preventing light leakage from the heat dissipation channel 80 and affecting the function of other components inside the housing 10. The upper cover 73 and the base 71 together form the heat dissipation channel 80. The exhaust unit 51 is located in the first zone 701, and the heat dissipation channel 80, the light-emitting component 30 and the heat dissipation component 50 are all located in the second zone 702. At least part of the airflow blown out from the exhaust unit 51 can enter the second zone 702 from the exhaust port 511 and enter the heat dissipation channel 80, and take away the heat emitted by the light-emitting component 30 and the heat dissipation component 50 in the heat dissipation channel 80.
[0062] During the airflow process, the upper cover 73 and the base 71 are the two side walls of the heat dissipation channel 80. On the one hand, they can guide the flow direction of the airflow entering the heat dissipation channel 80. On the other hand, they can restrict the airflow from the direction perpendicular to the extension direction of the upper cover 73 and the direction perpendicular to the extension direction of the base 71. That is, the upper cover 73 and the base 71 can restrict the airflow from the third direction to the Z direction in the heat dissipation channel 80, which helps to gather the airflow in the heat dissipation channel 80, increase the airflow speed, thereby improve the heat dissipation efficiency and ensure that the heat generated by the light-emitting component 30 can be carried away.
[0063] Please see Figure 2 and Figure 3 In some embodiments, the top cover 73 includes a first side 7301 and a second side 7302 facing away from each other, a thermoelectric cooling unit 52 is disposed on the first side 7301, a light guiding unit 33 is disposed on the second side 7302, and a first heat-conducting element 551 is located between the thermoelectric cooling unit 52 and the light guiding unit 33.
[0064] Specifically, the top cover 73 includes a first side 7301 and a second side 7302 facing away from each other in the Z direction. The first side 7301 is further away from the light guide unit 33 than the second side 7302. The thermoelectric cooling unit 52 is supported on the first side 7301. The top cover 73 can provide some support for the thermoelectric cooling unit 52, preventing it from shifting during use and improving its fixation. The first heat-conducting element 551 can absorb the heat from the light-emitting component 30 and conduct the heat to the cold end 523 through thermal conduction.
[0065] Please see Figure 2 and Figure 3In some embodiments, the top cover 73 is provided with a through groove 732 that passes through the first side 7301 and the second side 7302. The first heat-conducting member 551 includes a first heat-conducting part 5511, a second heat-conducting part 5512 and a third heat-conducting part 5513 connected to the first heat-conducting part 5511 and the second heat-conducting part 5512. The first heat-conducting part 5511 is located on the first side 7301 and is connected to the thermoelectric cooling unit 52. The second heat-conducting part 5512 is located on the second side 7302 and is connected to the light-guiding unit 33. The third heat-conducting part 5513 passes through the through groove 732.
[0066] Specifically, the through slot 732 is used to connect the first side 7301 and the second side 7302. There can be one or more through slots 732. In this application, there is one through slot 732. The upper cover 73 has a through slot 732 opened along the third direction Z. The first heat-conducting element 551 can pass through the through slot 732, connecting the thermoelectric cooling unit 52 located on the first side 7301 and the light-guiding unit 33 located on the second side 7302. Further, the portion of the first heat-conducting element 551 located on the first side 7301 is a first heat-conducting part 5511, which is sandwiched between the thermoelectric cooling unit 52 and the first side 7301 of the upper cover 73. The first heat-conducting part 5511 can transfer heat from the light-guiding unit 33 to the thermoelectric cooling unit 52. The portion of the first heat-conducting element 551 located on the second side 7302 is a second heat-conducting part 5512, which is sandwiched between the light-guiding unit 33 and the upper cover 73. Between the first side 7301, the second heat-conducting part 5512 can absorb the heat from the light-guiding unit 33 and transfer it to the first heat-conducting part 5511; the portion of the first heat-conducting element 551 located in the through groove 732 is the third heat-conducting part 5513, which connects the first heat-conducting part 5511 and the second heat-conducting part 5512. The third heat-conducting part 5513 can transfer the heat from the second heat-conducting part 5512 to the first heat-conducting part 5511, and thus to the thermoelectric cooling unit 52. The through groove 732 can shorten the length of the first heat-conducting element 551, thereby shortening the heat conduction path length between the thermoelectric cooling unit 52 and the heat-conducting unit 55, thereby improving the heat conduction efficiency.
[0067] Please see Figure 2 and Figure 3 In some embodiments, the upper cover 73 is further provided with an upper cover extension wall 734, which is located on the first side 7301 and extends protruding from the second side 7302 toward the first side 7301. The exhaust unit 51 and the thermoelectric cooling unit 52 are located on opposite sides of the upper cover extension wall 734, respectively.
[0068] Specifically, the upper cover 73 is provided with an upper cover extension wall 734 extending Z-direction. In some embodiments, the upper cover extension wall 734 and the upper cover 73 are an integral structure, that is, the upper cover extension wall 734 and the upper cover 73 are a single unit, thereby improving the bonding strength between the upper cover extension wall 734 and the upper cover 73, preventing separation of the upper cover extension wall 734 and the upper cover 73 during the operation of the base 71, thus ensuring the stability and reliability of the base 71 during operation. In other embodiments, the upper cover extension wall 734 and the upper cover 73 are separate structures, that is, the upper cover extension wall 734 and the upper cover 73 are two different structures. In one example, the upper cover extension wall 734 and the upper cover 73 can be joined together by a detachable connection method, including but not limited to snap-fit connections or threaded connections. In another example, the upper cover extension wall 734 and the upper cover 73 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.
[0069] In the first direction X, the exhaust unit 51 and the thermoelectric cooling unit 52 are located on opposite sides of the upper cover extension wall 734. The upper cover extension wall 734 can isolate the exhaust unit 51, preventing the airflow carrying heat after heat exchange from being blown out by the exhaust unit 51 from blowing onto the thermoelectric cooling unit 52, thereby ensuring the cooling effect of the thermoelectric cooling unit 52.
[0070] Please see Figure 2 and Figure 3 In some embodiments, the base 71 is provided with a receiving groove 714, and the light-emitting unit 31 is at least partially received in the receiving groove 714.
[0071] Specifically, the receiving slot 714 is used to receive the light-emitting unit 31. There can be one or more receiving slots 714; in this application, there is one receiving slot 714, and the base 71 has the receiving slot 714 along the second direction Y. The receiving slot 714 is connected to the heat dissipation channel 80, meaning that the space within the receiving slot 714 can serve as part of the heat dissipation channel 80. After airflow exits from the exhaust port 511, the airflow passes through the receiving slot 714 and the heat dissipation channel 80, carrying away the heat from the light-emitting component 30 to dissipate heat from the light-emitting component 30.
[0072] The receiving slot 714 can increase the space for airflow in the heat dissipation channel 80, thereby increasing the flow area of airflow in the heat dissipation channel 80 and enhancing the heat dissipation effect on the light-emitting component 30. On the other hand, it can increase the space inside the housing 10 in the third direction Z, thereby setting a larger light-emitting unit 31 in the third direction Z, thereby improving the hair removal efficiency.
[0073] Please see Figure 2 and Figure 3In some embodiments, the heat dissipation assembly 50 further includes a heat dissipation unit 53, which is connected to the hot end 521 of the thermoelectric cooling unit 52. The thermoelectric cooling unit 52 is used to absorb the heat generated by the light-emitting component 30 through the first heat-conducting element 551 and transfer it to the heat dissipation unit 53.
[0074] Specifically, the heat dissipation unit 53 is made of a material with good thermal conductivity. The heat dissipation unit 53 can absorb heat from the thermoelectric cooling unit 52 and conduct the heat to its surface through thermal conduction. The surface of the heat dissipation unit 53 has a certain contact area with the air. When the airflow blown from the exhaust port passes over the surface of the heat dissipation unit 53, the airflow absorbs and carries away the heat from the heat dissipation unit 53 and is blown out from the exhaust port 15. The heat dissipation unit 53 includes multiple heat sinks, which increase the contact area between the heat dissipation unit 53 and the surrounding air, promoting heat exchange between the heat and the airflow. The outer contour shape of the heat sinks includes, but is not limited to, flat, finned, and wavy shapes. The heat sinks can be made of various materials, including but not limited to aluminum, copper, steel, plastic, or carbon composite materials, and are not limited in this application. The shapes and materials of the multiple heat sinks can be the same or different. The areas of the multiple heat sinks can be the same, which is beneficial for manufacturing and ensures consistent heat dissipation performance of the heat dissipation unit 53. The areas of the multiple heat sinks can also be different.
[0075] Please see Figure 2 and Figure 4 In some embodiments, the projection of the heat dissipation unit 53 on the base 71 at least covers a portion of the second area 702 and is used to form a heat dissipation duct.
[0076] Specifically, in the XY projection plane, the projection of the heat dissipation unit 53 at least covers the second region 702. Further, the heat dissipation unit 53 of this application extends towards the base 71 on both sides of the second direction Y, thereby forming a first portion in the XY plane and a second portion on both sides of the second direction Y and located in the XZ plane. The first portion, the second portion, and the base 71, as sidewalls of the heat dissipation duct, together form the heat dissipation duct. After the airflow exits from the exhaust port, the airflow can carry away the heat dissipated by the heat dissipation unit 53 in the second region 702 and blow the heat out from the exhaust port 15. The projection of the heat dissipation unit 53 at least covers the second region 702, providing a large coverage area and improving the heat dissipation effect.
[0077] Please see Figure 2 and Figure 3In some embodiments, in the direction from the thermoelectric cooling unit 52 to the heat dissipation unit 53, the heat dissipation unit 53 includes a first surface 531 and a second surface 532 facing away from each other, with the first surface 531 being closer to the thermoelectric cooling unit 52 than the second surface 532; the heat conduction unit 55 includes a second heat conduction element 552, which is located between the hot end 521 of the thermoelectric cooling unit 52 and the first surface 531, and is used to absorb the heat of the thermoelectric cooling unit 52 and transfer it to the heat dissipation unit 53.
[0078] Specifically, on the third direction Z, the heat dissipation unit 53 includes a first surface 531 and a second surface 532 facing away from each other. The second heat-conducting element 552 is located between the hot end 521 of the thermoelectric cooling unit 52 and the first surface 531. The heat from the thermoelectric cooling unit 52 can be transferred to the second heat-conducting element 552, and thus to the heat dissipation unit 53. The material of the second heat-conducting element 552 can be graphite, graphene, copper, aluminum, diamond, etc. In this application, the second heat-conducting element 552 is made of graphite. Graphite has good thermal conductivity, low cost, and low density, which can reduce the weight of the skin care device 100 and make it easier for the user to hold. There can be one or more second heat-conducting elements 552; in this application, there is one.
[0079] The second heat-conducting element 552 is located between the hot end 521 of the thermoelectric cooling unit 52 and the first surface 531, which can enhance the heat conduction efficiency between the hot end 521 and the heat dissipation unit 53.
[0080] Please see Figure 2 and Figure 3 In some embodiments, the heat-conducting unit 55 includes a third heat-conducting element 553, which is located between the housing 10 and the second surface 532. The third heat-conducting element 553 is used to absorb the heat from the heat dissipation unit 53 and transfer it to the housing 10.
[0081] Specifically, the material of the third heat-conducting element 553 can be graphite, graphene, copper, aluminum, diamond, etc. The second heat-conducting element 552 in this application uses graphite, which has good thermal conductivity, low cost, and low density, reducing the weight of the skin care device 100 and making it easier for the user to hold. There can be one or more third heat-conducting elements 553; in this application, there is one. The third heat-conducting element 553 is located between the housing 10 and the second surface 532, enhancing the diffusion rate of heat within the heat dissipation unit 53, thereby improving the heat conduction efficiency between the housing 10 and the second surface 532.
[0082] Please see Figure 2 and Figure 3In some embodiments, the base 71 further includes a first extension wall 713 disposed on the seat body 711. The first extension wall 713 extends from the seat body 711 along the thickness direction of the skin care device 100 and serves as the side wall of the heat dissipation channel 80. The exhaust unit 51 and the light-emitting component 30 are located on opposite sides of the first extension wall 713, and the air outlet 15 and the light-emitting component 30 are located on the same side of the first extension wall 713. The first extension wall 713 is provided with an air inlet 7131, which is connected to the exhaust port 511 of the exhaust unit 51. The opposite ends of the heat dissipation channel 80 are connected to the air inlet 7131 and the air outlet 15, respectively.
[0083] Specifically, the base 711 is provided with a first extension wall 713 extending Z in a third direction. In some embodiments, the first extension wall 713 and the base 711 are an integral structure, that is, the first extension wall 713 and the base 711 are a single unit, thereby improving the bonding strength between the first extension wall 713 and the base 711 and preventing separation of the first extension wall 713 and the base 711 during operation, thus ensuring the stability and reliability of the base 71 during operation. In other embodiments, the first extension wall 713 and the base 711 are separate structures, that is, the first extension wall 713 and the base 711 are two different structures. In one example, the first extension wall 713 and the base 711 can be joined together by a detachable connection method, including but not limited to snap-fit connections or threaded connections. In another example, the first extension wall 713 and the base 711 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.
[0084] The first extension wall 713 is used to separate the first region 701 and the second region 702. The first extension wall 713 includes two opposite sides in the first direction X, the exhaust unit 51 is located on the side of the first extension wall 713 away from the light outlet 11, and the light-emitting component 30 is located on the side of the first extension wall 713 closer to the light outlet 11. The first extension wall 713 has a certain length in the second direction Y to separate the first region 701 and the third region in the first direction X. The first extension wall 713 is spaced from the side wall of the housing 10 in the second direction Y. Thus, the portion that is spaced and opposite to the exhaust port 511 is the air inlet 7131. The air inlet 7131 is connected to the exhaust port 511 of the exhaust unit 51, and the opposite ends of the heat dissipation channel 80 are connected to the air inlet 7131 and the air outlet 15, respectively. The airflow discharged from the exhaust port 511 of the exhaust unit 51 can enter the heat dissipation channel 80 through the air inlet 7131, and carry away the heat generated by the light-emitting component 30 located on the heat dissipation channel 80 before being blown out from the air outlet 15, thereby completing the heat dissipation of the light-emitting component 30. During the airflow process, the first extension wall 713, as the side wall of the channel, can guide the flow of air entering the heat dissipation channel 80 and prevent the air from flowing back to the exhaust unit 51.
[0085] Since the air inlet 7131 on the first extension wall 713 is connected to the exhaust port 511 of the exhaust unit 51, and the two ends of the heat dissipation channel 80 are respectively connected to the air inlet 7131 and the exhaust port 15, the airflow discharged from the exhaust port 511 of the exhaust unit 51 can enter the heat dissipation channel 80 through the air inlet 7131, and carry away the heat generated by the light-emitting component 30 located on the heat dissipation channel 80 before being blown out from the exhaust port 15, thereby completing the heat dissipation of the light-emitting component 30. During the airflow process, the first extension wall 713, as the side wall of the heat dissipation channel 80, can guide the flow direction of the airflow entering the heat dissipation channel 80 and prevent the air from flowing back to the exhaust unit 51.

[0089] Specifically, the skin care device 100 can be placed directly on the sterilization base 500, or it can be connected to the sterilization base 500 via a connector to secure the skin care device 100. The sterilization base 500 provides stable support for the skin care device 100 to prevent it from tipping over or being moved. Furthermore, the sterilization base 500 can sterilize the skin care device 100 using a sterilization medium, including but not limited to ultraviolet light and sterilizing liquids.
[0090] Please see Figure 2 and Figure 5 In some embodiments, the care system 1000 also includes a protective shield 700 for blocking light emitted by the skin care device 100.
[0091] Specifically, during the use of the skin care device 100, the user can wear a protective shield 700 to prevent the light emitted by the skin care device 100 from harming the eyes. The protective shield 700 can be a shield structure that covers the eyes or a pair of glasses.
[0092] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, the care system 1000 also includes an adapter head 800. The adapter head 800 is detachably connected to the light outlet 11 and is used to modulate the light emitted from the light outlet 11 to the outside, so that the modulated light is suitable for the care needs of different skin locations.
[0093] Specifically, the adapter head 800 can modulate the light emitted from the light outlet 11 to the outside. Modulation includes, but is not limited to, adjusting the size, shape, and light intensity of the light-emitting area of the light outlet 11 to adapt to the care needs of different skin locations. The adapter head 800 includes, but is not limited to, lip adapter heads and underarm adapter heads. For example, when treating skin areas requiring meticulous care, such as the lips and underarms, users can install the corresponding lip adapter head or underarm adapter head at the light outlet 11 to achieve a better hair removal experience.
