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, skin care devices (such as hair removal devices) typically have air inlets on their casings. The heat dissipation components inside the hair removal device need to draw in external airflow from the air inlet for internal heat dissipation. However, when users hold and use the hair removal device, their hands can easily block the air inlet, affecting the heat dissipation efficiency of the device. 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 shielding plate, a light-emitting component, and a heat dissipation component. The housing has a first air inlet and a first air outlet. The shielding plate is disposed outside the housing and connected to it. The projection of the shielding plate onto the housing covers the first air inlet, and a gap exists between the shielding plate and the housing, the gap communicating with the first air inlet. The light-emitting component is housed inside the housing and is used to emit light to the outside of the skin care device. The heat dissipation component includes an exhaust unit, which draws air in from outside the housing through the first air inlet, passes through the light-emitting component, and then discharges it from the first air outlet.

[0005] In the skin care device of this application, a shield is provided at the first air inlet to prevent the human hand from covering the first air inlet when the human body holds the shell, thereby ensuring that the first air inlet is unobstructed; the gap is connected to the first air inlet, so the airflow can pass through the gap through the first air inlet into the exhaust unit and then be introduced into the shell. The airflow flows in the shell at a certain air pressure and speed. During the flow of the airflow in the shell, it can continuously absorb and carry away the heat generated by the light-emitting component inside the shell. The airflow carrying heat is discharged to the external environment through the first air outlet, thereby reducing the temperature inside the shell.

[0006] In some embodiments, the shielding plate includes a first surface and a second surface opposite to each other, the second surface being closer to the housing than the first surface, and a support member is provided on the second surface, the support member abutting against the housing. When a user holds the housing and applies force to the shielding plate, the support member abuts against the housing, providing support for the shielding plate and preventing it from deforming under the applied force, thereby ensuring unobstructed passage of the gap.

[0007] In some embodiments, the second side is provided with a buckle, and the housing is provided with a buckle groove that cooperates with the buckle. The buckle is connected to the buckle groove, and the detachable connection between the buckle and the buckle groove is beneficial for the replacement and maintenance of the shield.

[0008] In some embodiments, the second side is provided with a snap-fit ​​groove, and the housing is provided with a snap-fit ​​that cooperates with the snap-fit. The snap-fit ​​groove is connected to the snap-fit, and the detachable connection between the snap-fit ​​and the snap-fit ​​groove is beneficial for the replacement and maintenance of the shield.

[0009] In some embodiments, a dust filter is provided inside the first air inlet. The dust filter allows airflow to pass through while blocking dust particles from the outside of the housing from entering the housing. The dust filter has multiple micropores. On the one hand, dust particles larger than the pore size cannot pass through the dust filter, thereby preventing dust particles from entering the housing through the first air inlet and reducing the risk of contamination of the components inside the housing. On the other hand, airflow drawn in from the first air inlet can pass through the pores and enter the housing, ensuring efficient airflow.

[0010] In some embodiments, the skin care device further includes a support. The support is disposed within the housing, and the exhaust unit and the light-emitting component are both located on the support. The support forms a channel, one end of which communicates with the exhaust port of the exhaust unit, and the other end communicates with the first air outlet. The light-emitting component is located on the channel. Therefore, airflow passing through the channel can carry away heat from the light-emitting component, thus dissipating heat from the component.

[0011] In some embodiments, the channel includes a first channel; the support includes a base and a top cover. The base has a first area and a second area, and the exhaust unit is located in the first area. The top cover is disposed in the second area and together with the base forms the first channel, and the light-emitting component is located within the first channel. During airflow, the top cover and the base serve as two sidewalls of the first channel, which can guide the flow of air entering the first channel and help to concentrate the airflow in the first channel, thereby increasing the airflow velocity and improving heat dissipation efficiency, ensuring that the heat generated by the light-emitting component can be carried away.

[0012] In some embodiments, the upper cover has a first groove, and the base has a second groove, both of which communicate with the first channel. The communication between the first and second grooves and the first channel increases the space for airflow within the first channel, thereby increasing the flow area of ​​the airflow in the first channel and enhancing the heat dissipation effect on the light-emitting component.

[0013] 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 side wall of the channel. The exhaust unit and the light-emitting component are located on opposite sides of the first extension wall, and the first 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 that communicates with the exhaust port of the exhaust unit. The opposite ends of the first channel are respectively connected to the air inlet and the first air outlet. Since the air inlet communicates with the exhaust port of the exhaust unit, and the opposite ends of the first channel are respectively connected to the air inlet and the first air outlet, the airflow discharged from the exhaust port of the exhaust unit can enter the first channel through the air inlet, carry away the heat generated by the light-emitting component located on the first channel, and then be discharged from the first air outlet, thereby completing the heat dissipation of the light-emitting component. During the airflow process, the first extension wall, as a side wall of the channel, can guide the flow of air entering the first channel and prevent airflow from flowing back to the exhaust unit.

[0014] In some embodiments, the base further includes a third zone located between the first and second zones. The base and / or the top cover includes a second extending wall that extends along the thickness direction of the skin care device and is spaced from the first extending wall. The first extending wall separates the first and second zones, and the second extending wall separates the third zone and the second zone. The first air outlet is located in the third zone. The second extending wall blocks light scattering from the light-emitting component located in the second zone to the first and second zones, preventing light from affecting the exhaust unit.

[0015] In some embodiments, the channel further includes a second channel, and the heat dissipation assembly further includes a heat dissipation unit. The heat dissipation unit is connected to the bracket and at least covers the third area. The heat dissipation unit, the base, the first extension wall, and the second extension wall together form the second channel. The air inlet and the first air outlet are located at opposite ends of the second channel, and the second channel communicates with the first channel. During airflow, the heat dissipation unit, the base, the first extension wall, and the second extension wall serve as the four side walls of the second channel, guiding the flow of air entering the second channel and preventing air from flowing back to the exhaust unit. Furthermore, they help to concentrate airflow in the second channel, preventing airflow dissipation and increasing airflow velocity, thereby improving heat dissipation efficiency.

[0016] In some embodiments, the second extension wall is provided with a second air inlet and a second air outlet, which are respectively the opposite ends of the first channel in the airflow direction. The second air inlet connects the first channel and the second channel, and the second air outlet connects the first channel and the second channel. In the airflow direction, the second air inlet is closer to the air inlet than the second air outlet. Part of the airflow discharged from the exhaust port enters the second channel through the air inlet, carries away heat from the second channel, and is then discharged through the first air outlet; the other part passes through the second channel, enters the first channel through the second air inlet, carries away heat from the first channel, enters the first channel through the second air outlet, and is then discharged to the outside through the first air outlet.

[0017] In some embodiments, the second extension wall has a first protrusion at one end near the second air outlet. The first protrusion extends from the first channel toward the second channel and serves to prevent the airflow exiting the second air outlet from flowing back into the second channel toward the second air inlet, and to guide the airflow entering the second channel from the air inlet toward the first air outlet. The first protrusion is located in the direction of airflow from the second channel to the first air outlet, preventing the airflow exiting the second channel from colliding with the airflow exiting the first channel, and avoiding the airflow exiting the second air outlet from flowing back into the second channel toward the second air inlet. Furthermore, the first protrusion also guides the airflow entering the second channel from the air inlet toward the first air outlet.

[0018] In some embodiments, the second extension wall has a second protrusion at one end near the first air inlet. The second protrusion extends from the first channel toward the second channel and is used to block light emitted by the light-emitting component and emitted from the first air inlet. Part of the light emitted by the light-emitting component will escape from the second air inlet. The second protrusion, located between the second air inlet and the first air outlet, can block the light emitted from the second air inlet from escaping through the first air outlet. In some embodiments, the bracket has a third extension wall located between the first air outlet and the second air outlet. The third extension wall is used to block light emitted by the light-emitting component and emitted from the second air outlet. Part of the light emitted by the light-emitting component will escape from the second air outlet. The third extension wall, located between the first air outlet and the second air outlet, can block the light emitted from the second air outlet from escaping through the first air outlet.

[0019] In some embodiments, the skin care device further includes a seal sandwiched between the housing and the support in the direction of airflow outward from the first air outlet, and at least partially covering the first air outlet. The seal allows airflow to pass through and exit from the first air outlet to the outside of the housing, and prevents airflow from flowing back into the housing from between the housing and the support. The seal seals the gap between the housing and the support, preventing heat-laden airflow from the exhaust vent from flowing back into the housing through the gap and being drawn back into the exhaust unit, thereby ensuring the heat dissipation efficiency of the skin care device.

[0020] In some embodiments, the seal includes a first portion and a second portion, the second portion being disposed around the first portion. The first portion has an opening, and in the direction of airflow from the first air outlet, the first portion at least partially covers the first air outlet. The opening communicates with the first air outlet, and the second portion is used to seal the gap between the housing and the support. The opening in the first portion prevents dust particles larger than the opening size from passing through, thus blocking dust particles from entering the housing through the first air outlet and reducing the risk of contamination of the components inside the housing. Furthermore, airflow can pass through the opening and exit to the external environment after passing through the channel, thereby carrying away heat from inside the housing. The second portion is used to seal the gap between the housing and the support.

[0021] In some embodiments, the first part is foam. Foam has good flexibility and toughness, effectively absorbing external impact forces, reducing wear caused by contact between the housing and the support, and protecting internal components from damage. Foam is lightweight, reducing the overall weight of the skin care device.

[0022] In some embodiments, the second part is a dust filter. The dust filter has multiple tiny pores. On the one hand, dust particles larger than the pore size cannot pass through the dust filter, thereby preventing dust particles from entering the housing through the first air outlet and reducing the risk of contamination of the components inside the housing. On the other hand, after passing through the channel, the airflow can pass through the pores and flow out to the external environment, thereby carrying away the heat inside the housing.

[0023] This application also provides a care system. The care system includes the skin care device described in any of the above embodiments. The skin care device of the care system has a shield at the first air inlet, which can prevent the human hand from covering the first air inlet when the human body holds the shell, thereby ensuring that the first air inlet is unobstructed; the gap is connected to the first air inlet, so the airflow can pass through the gap through the first air inlet and enter the exhaust unit and then be introduced into the shell. The airflow flows in the shell at a certain air pressure and speed. During the flow of the airflow in the shell, it can continuously absorb and carry away the heat generated by the light-emitting component inside the shell. The airflow carrying heat is discharged to the external environment through the first air outlet, thereby realizing the reduction of the internal temperature of the shell.

[0024] In some embodiments, the care system further includes a charging component. The charging component is used to charge 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 placement bracket. The placement bracket is used to hold the skin care device. The placement bracket provides stable support for the skin care device to prevent it from tipping over or being moved.

[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.

Detailed Implementation

[0039] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0040] 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.

[0041] 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.

[0042] Please see Figures 1 to 3 The skin care device 100 according to this application includes a housing 10, a shielding plate 20, a light-emitting component 30, and a heat dissipation component 50. The housing 10 is provided with a first air inlet 13 and a first air outlet 15. The shielding plate 20 is disposed on the outside of the housing 10 and connected to the housing 10. The projection of the shielding plate 20 on the housing 10 covers the first air inlet 13, and there is a gap 203 between the shielding plate 20 and the housing 10, which communicates with the first air inlet 13. The light-emitting component 30 is housed inside the housing 10 and is used to emit light to the outside of the skin care device 100. The heat dissipation component 50 includes an exhaust unit 51, which is used to draw air from the outside of the housing 10 through the first air inlet 13, and discharge it from the first air outlet 15 after flowing through the light-emitting component 30.

[0043] 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.

[0044] The first air inlet 13 penetrates the housing 10, connecting the outside and inside of the housing 10. The exhaust unit 51 inside the housing 10 can draw airflow from the outside of the housing 10 through the first air inlet 13 for heat dissipation inside the housing 10. There can be one or more first air inlets 13; in this application, there is only one. The first air inlet 13 can be located at any position on the housing 10 except for the light outlet 11. For example, the first air inlet 13 is located on the top wall of the housing 10. The top wall of the housing 10 has a larger area than the side walls, so the size of the first air inlet 13 can be further increased to improve the exhaust efficiency of the exhaust unit 51. In the first direction, the user typically holds the end of the housing 10 away from the light outlet 11. Therefore, in this application, the first air inlet 13 is located at the end of the housing 10 closer to the light outlet 11 than the user's holding part, to prevent the user's hand from obstructing the first air inlet 13. The shape of the first air inlet 13 projected onto the housing 10 includes, but is not limited to, a perfect circle, an ellipse, or a polygon. In this application, the first air inlet 13 is projected as an ellipse. An ellipse has no sharp corners, making it less likely to trap dirt and grime, and preventing dust carried by external airflow from depositing on the side wall of the first air inlet 13.

[0045] The first air outlet 15 penetrates the housing 10, connecting the outside and inside of the housing 10. The exhaust unit 51 inside the housing 10 draws airflow from the outside of the housing 10 and discharges it into the housing 10. The airflow can carry away the heat from the internal components of the housing 10 and flows out from the first air outlet 15 to the outside of the housing 10, thereby cooling the skin care device 100. There can be one or more first air outlets 15; in this application, there are multiple first air outlets 15. The first air outlet 15 can be located at any position on the housing 10 except for the light outlet 11. For example, the first air outlet 15 is located on the side wall of the housing 10. Thus, the airflow discharged from the first air outlet 15 flows out to the outside in a second direction. Correspondingly, the airflow drawn into the housing 10 from the first air inlet 13 is drawn into the housing 10 from a third direction. Therefore, the direction of the airflow discharged from the first air outlet 15 and the airflow drawn into the housing 10 from the first air inlet 13 is separated, which can prevent the relatively hot airflow discharged from the first air outlet 15 from being drawn back into the housing 10 from the first air inlet 13, thus avoiding affecting the heat dissipation efficiency. The shape of the projection of the first 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 first air outlet 15 is projected as an ellipse. An ellipse has no sharp corners, making it less likely to trap dirt and grime, and preventing dust carried by the external airflow from depositing on the side wall of the first air outlet 15.

[0046] The shielding plate 20 is disposed on the outside of the housing 10 and connected to the housing 10. In some embodiments, the shielding plate 20 and the housing 10 are an integral structure, that is, the shielding plate 20 and the housing 10 are a single unit, thereby improving the bonding strength between the shielding plate 20 and the housing 10 and preventing separation of the shielding plate 20 and the housing 10 during operation of the skin care device 100, thus ensuring the stability and reliability of the skin care device 100 during operation. In other embodiments, the shielding plate 20 and the housing 10 are separate structures, that is, the shielding plate 20 and the housing 10 are two different structures. In one example, the shielding plate 20 and the housing 10 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connection 23 or threaded connection. In another example, the shielding plate 20 and the housing 10 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.

[0047] The projection of the shield 20 onto the housing 10 covers the first air inlet 13; that is, the projection of the shield 20 onto the XY plane covers the first inlet. Thus, when a user holds the housing 10, the shield 20 can protect the first inlet, preventing the user's hand from covering it. The shape of the shield 20 projected onto the housing 10 includes, but is not limited to, a perfect circle, an ellipse, or a polygon. In this application, the shield 20 is projected as an ellipse. An ellipse has no sharp corners, so it will not scratch the user. The ellipse also corresponds to the shape of the first air inlet 13, allowing the first air inlet 13 to be covered with less material.

[0048] Furthermore, a gap 203 exists between the baffle 20 and the housing 10, and the gap 203 communicates with the first air inlet 13. Thus, external airflow can enter the first air inlet 13 through the gap 203 and then be drawn into the housing 10. In this application, the gap 203 is the space between the outer surface of the baffle 20 and the housing 10 in a third direction. The gap 203 surrounds the baffle 20, so that external airflow can enter the gap 203 from multiple directions. The baffle 20 and the housing 10 can be made of rigid materials, such as aluminum, stainless steel, copper, polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), or polybutylene terephthalate (PBT). The material of the shielding plate 20 can be the same as that of the housing 10. For example, both the shielding plate 20 and the housing 10 can be made of PP material. Alternatively, the material of the shielding plate 20 and the housing 10 can be different. For example, both the shielding plate 20 and the housing 10 can be made of PP material.

[0049] The light-emitting component 30 is used to emit specific light to the outside. The light-emitting component 30 includes a light-emitting unit 31 and a light-guiding unit 33. The light-guiding unit 33 in this application is made of sapphire. The light-emitting unit 31 emits light and directs it towards the human skin to achieve hair removal. The sapphire is positioned in the light path. On the one hand, the light-guiding unit 33 can guide the light to the outside of the housing 10; on the other hand, the light-emitting unit 31 generates a large amount of heat during use. Sapphire has high thermal conductivity, which can quickly conduct the heat from the light-emitting unit 31 to the heat dissipation component 50, thereby reducing skin temperature and minimizing discomfort and potential skin damage during the hair removal process.

[0050] The heat dissipation assembly 50 is used to dissipate heat from the components inside the housing 10. The heat dissipation assembly 50 includes an exhaust unit 51, which is an axial fan. The air inlet and outlet of the axial fan are not in the same direction, meaning that the air duct of the axial fan itself can be flexibly set to guide airflow into and out of the axial fan from different directions. The axial fan of this application draws in airflow in a third direction and discharges airflow in a second direction, which is beneficial for the flexible layout of the axial fan inside the housing 10. The exhaust unit 51 can draw in airflow from outside the housing 10 through the gap 203 and the first inlet and guide it into the housing 10. After that, the airflow is discharged into the housing 10 at a certain pressure and speed. The airflow flows in the housing 10 at a certain pressure and speed. During the flow of the airflow in the housing 10, it can continuously absorb and carry away the heat generated by the internal components. The airflow carrying heat is discharged to the external environment through the first outlet 15, thereby reducing the internal temperature of the housing 10.

[0051] In the skin care device 100 of this application, a shield 20 is provided at the first air inlet 13 to prevent the human hand from covering the first air inlet 13 when the human body holds the shell 10, thereby ensuring that the first air inlet 13 is unobstructed; the gap 203 is connected to the first air inlet 13, so the airflow can pass through the gap 203 through the first air inlet 13 and enter the exhaust unit 51 and then be introduced into the shell 10. The airflow flows in the shell 10 with a certain air pressure and speed. During the flow of the airflow in the shell 10, it can continuously absorb and carry away the heat generated by the light-emitting component 30 inside the shell 10. The airflow carrying heat is discharged to the external environment through the first air outlet 15, thereby realizing the reduction of the internal temperature of the shell 10.

[0052] Please see Figures 2 to 4 In some embodiments, the shielding plate 20 includes a first surface 201 and a second surface 202 opposite to each other. The second surface 202 is closer to the housing 10 than the first surface 201. The second surface 202 is provided with a support member 21, which abuts against the housing 10.

[0053] Specifically, in the third direction, the shielding plate 20 includes a first surface 201 and a second surface 202 facing each other. A support member 21 is provided, located between the second surface 202 and the housing 10, to support the shielding plate 20. The number of support members 21 can be, but is not limited to, one, two, three, four, or more. For example, when there is only one support member 21, one support member 21 can surround the second surface 202. In this case, the connection between the support member 21 and the shielding plate 20 is relatively stable, and the processing of the support member 21 and the shielding plate 20 is relatively simple. When there are multiple support members 21, the multiple support members 21 can be spaced apart on the second surface 202; preferably, the multiple support members 21 can be evenly distributed on the second surface 202. In this application, there are multiple support members 21, which are either annular support members 21 located at the center of the second surface 202, or strip-shaped support members 21 radially and evenly distributed around the annular support member 21.

[0054] When the user holds the housing 10 and applies force to the shield 20, the support 21 abuts against the housing 10, providing support for the shield 20 and preventing the shield 20 from deforming under the force, thereby ensuring the unobstructed flow of the gap 203.

[0055] Please see Figure 3 and Figure 4 In one embodiment, the second surface 202 is provided with a buckle 23, and the housing 10 is provided with a buckle 23 groove 17 that mates with the buckle 23. The buckle 23 and the buckle 23 groove 17 are connected in a cooperative manner. In another embodiment, the second surface 202 is provided with a buckle 23 groove 17, and the housing 10 is provided with a buckle 23 that mates with the buckle 23. The buckle 23 groove 17 is connected in a cooperative manner with the buckle 23. The detachable connection between the buckle 23 and the buckle 23 groove 17 facilitates the replacement and maintenance of the shielding plate 20. Furthermore, the second surface 202 is also provided with a positioning element 25, and the housing 10 is provided with a positioning groove 19 that mates with the positioning element 25 for positioning the shielding plate 20 during installation. The positioning element 25 can be one or more. In this application, there are two positioning elements 25 in the length direction. The two positioning elements 25 have different shapes, and correspondingly, the two positioning grooves 19 have different shapes, as a foolproof design to facilitate user identification of the installation position of the shielding plate 20 in the first direction.

[0056] Please see Figure 3 and Figure 4 In some embodiments, a dustproof net 40 is provided inside the first air inlet 13. The dustproof net 40 is used to allow airflow to pass through and to block dust particles outside the housing 10 from entering the interior of the housing 10.

[0057] Specifically, a dust filter 40 is installed inside the first air inlet 13. The dust filter 40 has multiple tiny pores. On the one hand, dust particles larger than the pore size cannot pass through the dust filter 40, thus preventing dust particles from entering the housing 10 through the first air inlet 13 and reducing the risk of contamination of the components inside the housing 10. On the other hand, the airflow drawn in from the first air inlet 13 can pass through the pores and enter the housing 10, ensuring efficient airflow. The material of the dust filter 40 can be high-density plastic fiber or metal wire, etc., and is not limited thereto. In one example, the dust filter 40 is installed on the side of the housing 10 located inside the housing 10. In another example, the housing 10 has a receiving groove inside, and the dust filter 40 is installed in the receiving groove, facing the first air inlet 13 in a third direction.

[0058] Please see Figures 2 to 4 In some embodiments, the skin care device 100 further includes a support 70. The support 70 is disposed inside the housing 10, and the exhaust unit 51 and the light-emitting component 30 are both located on the support 70. The support 70 forms a 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 first air outlet 15. The light-emitting component 30 is located on the channel 80.

[0059] Specifically, 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 gap 203 and enters the exhaust unit 51 through the first air inlet 13, the exhaust unit 51 discharges the airflow from the exhaust port 511. One end of the channel 80 is connected to the exhaust port 511 of the exhaust unit 51, so the airflow can flow directly into the channel 80 after being discharged from the exhaust unit 51 and is discharged to the outside of the housing 10 from the first air outlet 15. The light-emitting component 30 is located on the channel 80. The airflow passing through the channel 80 can carry away the heat of the light-emitting component 30 to dissipate heat from the light-emitting component 30.

[0060] Please see Figures 2 to 4 In some embodiments, channel 80 includes a first channel 81, and bracket 70 includes a base 71 and a top cover 73. The base 71 has a first zone 701 and a second zone 702, and the exhaust unit 51 is located in the first zone 701. The top cover 73 is disposed in the second zone 702 and together with the base 71 forms the first channel 81, and the light-emitting component 30 is located in the first channel 81.

[0061] Specifically, both the exhaust unit 51 and the light-emitting component 30 are housed within the base 71. This allows the base 71 to 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 can be made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composites. For example, when the base 71 is made of plastic, it offers good insulation, lower cost, and lighter weight. When the base 71 is made of a metal such as aluminum alloy, the housing 10 has higher strength, better wear resistance, and a longer service life. The top cover 73 is a structure within the bracket 70 that can cooperate with the base 71 to constrain the light-emitting component 30.

[0062] 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 may be the same as or different from the material of the base 71.

[0063] The base 71 has a first zone 701 and a second zone 702. In a first direction, the first zone 701 is further away from the light outlet 11 than the second zone 702. The upper cover 73 is disposed in the second zone 702, and in a third direction, 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. 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, preventing light leakage from the first channel 81 and affecting the function of other components inside the housing 10. The upper cover 73 and the base 71 together form the first channel 81, through which at least part of the airflow exhausted from the exhaust unit 51 enters and carries away the heat emitted by the light-emitting component 30 within the first channel 81.

[0064] During the airflow process, the upper cover 73 and the base 71 are the two side walls of the first channel 81. On the one hand, they can guide the flow direction of the airflow entering the first channel 81. 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 in the first channel 81, which helps to gather the airflow in the first channel 81, 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.

[0065] Please see Figures 2 to 4 In some embodiments, the upper cover 73 is provided with a first groove 731, and the base 71 is provided with a second groove 712. Both the first groove 731 and the second groove 712 are connected to the first channel 81.

[0066] Specifically, there can be one or more first grooves 731. In this application, there is one first groove 731, and the upper cover 73 is provided with the first groove 731 along the second direction. The first groove 731 is connected to the first channel 81, that is, the space in the first groove 731 can be part of the first channel 81. After the airflow is discharged from the exhaust port 511, the airflow passes through the first groove 731 and the first channel 81, and the air can carry away the heat of the light-emitting component 30 to dissipate heat from the light-emitting component 30.

[0067] The second groove 712 can be one or more. In this application, there is one second groove 712, and the base 71 has the second groove 712 along the second direction. The second groove 712 is connected to the first channel 81, that is, the space in the second groove 712 can be part of the first channel 81. After the airflow is discharged from the exhaust port 511, the airflow passes through the second groove 712 and the first channel 81, and the air can carry away the heat of the light-emitting component 30 to dissipate heat from the light-emitting component 30.

[0068] The first groove 731 and the second groove 712 are connected to the first channel 81, which can increase the space for airflow in the first channel 81, thereby increasing the flow area of ​​airflow in the first channel 81 and enhancing the heat dissipation effect on the light-emitting component 30.

[0069] Please see Figures 2 to 4 In some embodiments, the base 71 includes a seat body 711 and 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 channel 80. The exhaust unit 51 and the light-emitting component 30 are located on opposite sides of the first extension wall 713. The first 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 first channel 81 are connected to the air inlet 7131 and the first air outlet 15, respectively.

[0070] Specifically, the base 711 is provided with a first extension wall 713 extending 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, including but not limited to snap-fit ​​connection 23 or threaded connection. In another example, the first extension wall 713 and the base 711 can be joined together by a non-detachable connection, including but not limited to bonding or welding.

[0071] 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, 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 close to the light outlet 11. The first extension wall 713 has a certain length in the second direction to separate the first region 701 and the third region 703 in the first direction. The first extension wall 713 is spaced from the side wall of the housing 10 in the second direction. Thus, the portion that is spaced from and opposite 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 first channel 81 are connected to the air inlet 7131 and the first exhaust port 15, respectively. The airflow discharged from the exhaust port 511 of the exhaust unit 51 can enter the first channel 81 through the air inlet 7131, and carry away the heat generated by the light-emitting component 30 located on the first channel 81 before being discharged from the first 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 channel 80, can guide the flow of air entering the first channel 81 and prevent the air from flowing back to the exhaust unit 51.

[0072] Please see Figures 2 to 4 In some embodiments, the base 711 further includes a third zone 703 located between the first zone 701 and the second zone 702. The base 71 and / or the top cover 73 include a second extending wall 735 that extends along the thickness direction of the skin care device 100 and is spaced apart from the first extending wall 713. The second extending wall 735 serves to separate the third zone 703 from the second zone 702. A first air outlet 15 is located in the third zone 703.

[0073] Specifically, the base 711 is provided with a second extension wall 735 extending in a third direction. In some embodiments, the second extension wall 735 and the base 711 are an integral structure, that is, the second extension wall 735 and the base 711 are a single unit, thereby improving the bonding strength between the second extension wall 735 and the base 711 and preventing separation of the second extension wall 735 and the base 711 during operation, thus ensuring the stability and reliability of the base 71 during operation. In other embodiments, the second extension wall 735 and the base 711 are separate structures, that is, the second extension wall 735 and the base 711 are two different structures. In one example, the second extension wall 735 and the base 711 can be joined together by a detachable connection, including but not limited to snap-fit ​​connections 23 or threaded connections. In another example, the second extension wall 735 and the base 711 can be joined together by a non-detachable connection, including but not limited to bonding or welding.

[0074] The second extension wall 735 is used to separate the third region 703 and the second region 702. The second extension wall 735 includes two opposing sides in the first direction, with the third region 703 located on the side of the second extension wall 735 away from the light outlet 11, and the second region 702 located on the side of the second extension wall 735 closer to the light outlet 11. The second extension wall 735 has a certain length in the second direction to separate the second region 702 and the third region 703 in the first direction. The second extension wall 735 can block light scattering from the light-emitting component 30 located in the second region 702 to the first region 701 and the second region 702, preventing light from affecting the exhaust unit 51.

[0075] Please see Figures 2 to 4 In some embodiments, channel 80 further includes a second channel 83, and heat dissipation assembly 50 further includes a heat dissipation unit 53. The heat dissipation unit 53 is connected to the bracket 70 and at least covers the third area 703. The heat dissipation unit 53, base 71, first extension wall 713 and second extension wall 735 together form the second channel 83, with air inlet 7131 and first air outlet 15 located at opposite ends of the second channel 83, and the second channel 83 communicating with the first channel 81.

[0076] Specifically, the heat dissipation unit 53 is made of a material with good thermal conductivity. The heat dissipation component can absorb the heat from the light-emitting component 30 and conduct the heat to the surface of the heat dissipation unit 53 through thermal conduction. The surface of the heat sink has a certain contact area with the air. When the airflow discharged from the exhaust port passes over the surface of the heat sink, the airflow absorbs and carries away the heat from the heat sink. The surface of the heat sink also dissipates heat in the form of radiation. The heat dissipation unit 53 covers the third region 703, so the heat absorbed by the heat dissipation unit 53 from the light-emitting component 30 can diffuse into the third region 703. After the airflow is discharged from the exhaust port, the airflow can carry away the heat dissipated by the heat dissipation unit 53 in the third region 703 and discharge the heat from the first exhaust port 15.

[0077] The heat dissipation unit 53 also includes multiple heat sinks, which increase the contact area between the heat dissipation unit 53 and the surrounding air, promoting heat exchange between heat and 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 identical or different. The areas of the multiple heat sinks can be identical, which is beneficial for manufacturing processes and ensures consistent heat dissipation performance of the heat dissipation unit 53. The areas of the multiple heat sinks can also be different.

[0078] The heat dissipation unit 53, base 71, first extension wall 713, and second extension wall 735 together form the second channel 83. That is, the heat dissipation unit 53, base 71, first extension wall 713, and second extension wall 735 are the four side walls of the second channel 83. The second channel 83 is connected to the first channel 81, so the airflow discharged from the exhaust port 511 of the exhaust unit 51 can enter the first channel 81 through the air inlet 7131 and then enter the second channel 83, carrying away the heat located in the first channel 81 before being discharged from the first air outlet 15. The heat sources in the first channel 81 include, but are not limited to, the heat absorbed by the heat dissipation unit 53 from the light-emitting component 30, the heat generated by the operation of the exhaust unit 51, and the heat emitted by the light-emitting component 30.

[0079] During airflow, the heat dissipation unit 53, base 71, first extension wall 713, and second extension wall 735 serve as the four side walls of the second channel 83, guiding the flow of air entering the second channel 83 and preventing air from flowing back to the exhaust unit 51. On the other hand, they help to gather airflow in the second channel 83, preventing airflow from dissipating and increasing airflow velocity, thereby improving heat dissipation efficiency.

[0080] Please see Figures 2 to 4In some embodiments, the second extension wall 735 is provided with a second air inlet 7351 and a second air outlet 7353. The second air inlet 7351 and the second air outlet 7353 are the opposite ends of the first channel 81 in the airflow direction. The second air inlet 7351 connects the first channel 81 and the second channel 83, and the second air outlet 7353 connects the first channel 81 and the second channel 83. In the airflow direction, the second air inlet 7351 is closer to the air inlet 7131 than the second air outlet 7353.

[0081] Specifically, the second extension wall 735 has a certain length in the second direction to separate the first region 701 and the third region 703 in the first direction. The first extension wall 713 is spaced from the two opposite side walls of the housing 10 in the second direction. The space between the extension wall 713 and the side wall with the first air outlet 15 is the second air outlet 7353, and the space between the extension wall 713 and the side wall without the first air outlet 15 is the second air inlet 7351. Thus, the second extension wall 735 divides the airflow discharged from the exhaust port into two parts, that is, the airflow has two flow directions. Part of the airflow discharged from the exhaust port 511 enters the second channel 83 through the air inlet 7131, carries away the heat in the second channel 83, and is discharged from the first air outlet 15. The other part passes through the second channel 83, enters the first channel 81 through the second air inlet 7351, carries away the heat in the first channel 81, enters the first channel 81 through the second air outlet 7353, and is discharged to the outside through the first air outlet 15.

[0082] Please see Figures 2 to 4 In some embodiments, the second extension wall 735 is provided with a first protrusion 7355 at one end near the second air outlet 7353. The first protrusion 7355 extends protruding from the first channel 81 toward the second channel 83. The first protrusion 7355 is used to block the airflow flowing out of the second air outlet 7353 in the first channel 81 from flowing back toward the second channel 83 toward the second air inlet 7351, and to guide the airflow entering the second channel 83 from the air inlet 7131 toward the first air outlet 15.

[0083] Specifically, in some embodiments, the first protrusion 7355 and the second extension wall 735 are an integral structure, that is, the first protrusion 7355 and the second extension wall 735 are a single unit, thereby improving the bonding strength between the first protrusion 7355 and the second extension wall 735 and preventing separation of the first protrusion 7355 and the second extension wall 735 during the operation of the base 71, thus ensuring the stability and reliability of the base 71 during operation. In other embodiments, the first protrusion 7355 and the second extension wall 735 are separate structures, that is, the first protrusion 7355 and the second extension wall 735 are two different structures. In one example, the first protrusion 7355 and the second extension wall 735 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connection 23 or threaded connection. In another example, the first protrusion 7355 and the second extension wall 735 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.

[0084] After the airflow enters the first channel 81 and carries away the heat of the light-emitting component 30 inside the first channel 81, it flows out from the second air outlet 7353. The outflowing airflow tends to flow from the second air inlet 7351 towards the second channel 83, that is, the flow direction of the airflow out of the first channel 81 is roughly the same as the first direction. The airflow entering the second channel 83 flows out from the first air outlet 15, and tends to flow from the air inlet 7131 towards the first air outlet 15. The flow direction of the airflow out of the second channel 83 is roughly the same as the second direction. The first direction and the second direction are perpendicular. Therefore, near the first air outlet 15, the airflow out of the second channel 83 is likely to collide with the airflow out of the first channel 81.

[0085] The first protrusion 7355 is located in the direction of airflow from the second channel 83 to the first air outlet 15, which can prevent the airflow from the second channel 83 from colliding with the airflow from the first channel 81, and prevent the airflow from the second air outlet 7353 in the first channel 81 from flowing back towards the second inlet 7351 in the second channel 83. In addition, the first protrusion 7355 can also guide the airflow entering the second channel 83 from the air inlet 7131 towards the first air outlet 15.

[0086] Please see Figures 2 to 4 In some embodiments, the second extension wall 735 is provided with a second protrusion 7357 at one end near the first air inlet 13. The second protrusion 7357 extends protruding from the first channel 81 toward the second channel 83 and is used to block the light emitted by the light-emitting component 30 and emitted from the first air inlet 13.

[0087] Specifically, in some embodiments, the second protrusion 7357 and the second extension wall 735 are an integral structure, that is, the second protrusion 7357 and the second extension wall 735 are a single unit, thereby improving the bonding strength between the second protrusion 7357 and the second extension wall 735 and preventing separation of the second protrusion 7357 and the second extension wall 735 during the operation of the base 71, thus ensuring the stability and reliability of the base 71 during operation. In other embodiments, the second protrusion 7357 and the second extension wall 735 are separate structures, that is, the second protrusion 7357 and the second extension wall 735 are two different structures. In one example, the second protrusion 7357 and the second extension wall 735 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connection 23 or threaded connection. In another example, the second protrusion 7357 and the second extension wall 735 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.

[0088] Part of the light emitted by the light-emitting component 30 will be emitted from the second air inlet 7351. The second protrusion 7357 is located between the second air inlet 7351 and the first air outlet 15, and can block the light emitted from the second air inlet 7351 from being emitted from the first air outlet 15.

[0089] Please see Figures 2 to 4 In some embodiments, the bracket 70 is provided with a third extension wall 717, which is located between the first air outlet 15 and the second air outlet 7353. The third extension wall 717 is used to block the light emitted by the light-emitting component 30 and emitted from the second air outlet 7353.

[0090] Specifically, in some embodiments, the third extension wall 717 and the base 711 are an integral structure, that is, the third extension wall 717 and the base 711 are a single unit, thereby improving the bonding strength between the third extension wall 717 and the base 711 and preventing separation of the third extension wall 717 and the base 711 during operation, thus ensuring the stability and reliability of the base 71 during operation. In other embodiments, the third extension wall 717 and the base 711 are separate structures, that is, the third extension wall 717 and the base 711 are two different structures. In one example, the third extension wall 717 and the base 711 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connection 23 or threaded connection. In another example, the third extension wall 717 and the base 711 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.

[0091] Part of the light emitted by the light-emitting component 30 will be emitted from the second air outlet 7353. The third extension wall 717 is located between the first air outlet 15 and the second air outlet 7353, and can block the light emitted from the second air outlet 7353 from being emitted from the first air outlet 15.

[0092] Please see Figures 2 to 4 In some embodiments, the skin care device 100 further includes a seal 90, which is sandwiched between the housing 10 and the bracket 70 in the direction of airflow from the first air outlet 15 and at least partially covers the first air outlet 15. The seal 90 is used to allow airflow to pass through and flow out of the first air outlet 15 to the outside of the housing 10, and to prevent airflow from flowing back from between the housing 10 and the bracket 70 to the inside of the housing 10.

[0093] Specifically, the seal 90 is used to seal the gap 203 between the housing 10 and the bracket 70. The seal 90 can be made of materials such as rubber, silicone, plastic, or synthetic fibers. Among them, rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. There can be one or more seals 90, which is not limited in this application. In one example, the seal 90 is individually molded and sandwiched in the gap 203 between the housing 10 and the bracket 70, with an interference fit with the housing 10 and the bracket 70. It can also be connected to the housing 10 and / or the bracket 70, and the connection method includes, but is not limited to, bonding.

[0094] The seal 90 can seal the gap 203 between the housing 10 and the bracket 70, preventing the airflow carrying heat discharged from the exhaust port 511 from flowing back into the housing 10 through the gap 203 between the housing 10 and the bracket 70 and being sucked in again by the exhaust unit 51, thereby ensuring the heat dissipation efficiency of the skin care device 100.

[0095] Please see Figures 2 to 4 In some embodiments, the seal 90 includes a first part 91 and a second part 92. The second part 92 is disposed around the first part 91. The first part 91 is provided with an opening 911. In the direction of airflow from the first air outlet 15, the first part 91 at least partially covers the first air outlet 15. The opening 911 communicates with the first air outlet 15. The second part 92 is used to seal the gap 203 between the housing 10 and the bracket 70.

[0096] Specifically, the first part 91 has an opening 911. On the one hand, dust particles larger than the size of the opening 911 cannot pass through the first part 91, thus preventing dust particles from entering the interior of the housing 10 through the first air outlet 15, reducing the risk of contamination of the components inside the housing 10. On the other hand, after passing through the channel 80, the airflow can pass through the opening 911 and flow out to the external environment, thereby carrying away heat from inside the housing 10. The material of the first part 91 can be high-density plastic fiber or metal wire, etc., and is not limited thereto. It also conceals the internal components of the housing 10, preventing the user from seeing them through the first air outlet 15.

[0097] The second part 92 is used to seal the gap 203 between the housing 10 and the support 70. Soft and elastic materials such as foam, silicone, rubber, or polyvinyl chloride can be used. Rubber includes, but is not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. The first part 91 can recover its original shape after being subjected to force, effectively absorbing and dispersing the force. The second part 92, located between the housing 10 and the support 70, can absorb and reduce the forces that may be generated between the housing 10 and the support 70 due to impact and vibration, reducing damage to the housing 10 and the support 70. Furthermore, the second part 92 can reduce wear caused by the contact between the housing 10 and the support 70, helping to extend the service life of the housing 10 and the support 70.

[0098] Please see Figures 2 to 4 In some embodiments, the first part 91 is foam.

[0099] Specifically, the foam has good flexibility and toughness, effectively absorbing external impact forces, reducing wear caused by contact between the housing 10 and the support 70, and protecting the internal components of the device from damage. The foam is lightweight, which reduces the overall weight of the skin care device 100.

[0100] Please see Figures 2 to 4 In some embodiments, the second part 92 is a dustproof net 40.

[0101] Specifically, the dust filter 40 has multiple tiny pores. On the one hand, dust particles larger than the pore size cannot pass through the dust filter 40, thus preventing dust particles from entering the interior of the housing 10 through the first air outlet 15, reducing the risk of contamination of the components inside the housing 10. On the other hand, after passing through the channel 80, the airflow can pass through the pores and flow out to the external environment, thereby carrying away heat from inside the housing 10. The material of the dust filter 40 can be high-density plastic fiber or metal wire, etc., and is not limited thereto.

[0105] Specifically, the skin care device 100 can be placed directly on the placement bracket 500, or it can be connected to the placement bracket 500 via a connector to secure the skin care device 100. The placement bracket 500 provides stable support for the skin care device 100 to prevent it from tipping over or being moved.

[0106] Please see Figure 1 , 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.

[0107] 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.

[0108] 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.

[0109] Specifically, the adapter head 800 can modulate the light emitted from the light outlet 11 to the outside.
