Technical Field

[0004] In the related art, taking a hair removal device as an example, a skin care device generally only has one lamp tube as an IPL light source, resulting in poor skin care effects of the skin care device. Technical Solutions

[0005] The present invention provides a skin care device, comprising:

[0006] The housing is provided with a light outlet;

[0007] a light source assembly disposed in the housing, the light source assembly comprising a reflective component and at least two light sources, the light outlet being located on one side of the light source along the first direction, and the reflective component being at least partially located on a side of the light source facing away from the light outlet, so as to reflect part of the light from the light source toward the light outlet;

[0008] a circuit board disposed in the housing, the circuit board being provided on at least one side of the light source along a second direction, the second direction and the first direction being perpendicular to each other, the circuit board being electrically connected to the light source; and

[0009] The heat dissipation component is disposed in the housing, and at least a portion of the heat dissipation component is located on a side of the reflective component away from the light outlet. Beneficial effects

[0010] In the embodiment of the present application, the light source assembly can improve the care effect of the skin care device by emitting light from multiple light sources; for example, the multiple light sources can be switched on and off synchronously, so that the light source assembly can perform skin care at a higher maximum power, thereby improving the care effect of the skin care device; or, different light sources can emit light individually or in combination, so that the light source assembly has at least three light emission modes, so as to adjust to a more appropriate light emission mode according to the actual needs of the user, thereby improving the care effect of the skin care device. In addition, since the light source is the main heat source of the skin care device, as the number of light sources increases, the heat at the light source assembly also increases significantly. Compared with sandwiching the circuit board between the side of the reflective component away from the light outlet and the heat dissipation assembly, the embodiment of the present application arranges the circuit board on the other side of the light source, so that the distance between the heat dissipation assembly and the light source assembly can be closer, thereby shortening the heat dissipation path, so as to achieve a better heat dissipation effect for the light source assembly with multiple light sources, thereby avoiding overheating of the light source assembly due to the operation of multiple light sources and causing abnormal operation, and ultimately improving the skin care effect of the skin care device.

[0030] Hair removal devices and photorejuvenation devices are commonly used skin care devices in our daily lives. These devices primarily use IPL (intense pulsed light) to irradiate the user's skin, achieving effects such as hair removal and photorejuvenation.

[0031] In the related art, taking a hair removal device as an example, a skin care device generally only has one lamp tube as an IPL light source, resulting in poor skin care effects of the skin care device.

[0032] Based on this, embodiments of the present application provide a skin care device to improve skin care effects. The skin care device can be a hair removal device or a skin rejuvenation device, etc., for removing hair or rejuvenating the skin. Of course, the skin care device can also be some beauty device with hair removal or skin rejuvenation functions, which is not limited by the embodiments of the present application.

[0033] 1 and 2 , FIG1 is a perspective view of a skin care device according to an embodiment of the present application, and FIG2 is a schematic diagram of one embodiment of the skin care device shown in FIG1 . The skin care device may include a housing 100 , a light source assembly 200 , a circuit board 300 , and a heat dissipation assembly 400 .

[0034] The housing 100 may be provided with a light outlet 11. The light source assembly 200 is disposed in the housing 100. The light source assembly 200 includes a reflective component 21 and at least two light sources 22, and the light outlet 11 is located on one side of the light source 22 along the first direction H1. The reflective component 21 is at least partially located on the side of the light source 22 away from the light outlet 11, so as to reflect part of the light from the light source 22 to the light outlet 11. The circuit board 300 is disposed in the housing 100. The circuit board 300 is provided on at least one side of the light source 22 along the second direction H2, and the second direction H2 and the first direction H1 are perpendicular to each other. The circuit board 300 is electrically connected to the light source 22. The heat dissipation assembly 400 is disposed in the housing 100, and the heat dissipation assembly 400 is at least partially located on the side of the reflective component 21 away from the light outlet 11.

[0035] It is understood that the embodiments of the present application can improve the skin care effect of the skin care device by emitting light from multiple light sources 22. For example, the multiple light sources 22 can be turned on and off synchronously, so that the light source assembly 200 can perform skin care at a higher maximum power, thereby improving the skin care effect of the skin care device; alternatively, different light sources 22 can emit light individually or in combination, so that the light source assembly 200 can have at least three light emission modes, so that a more appropriate light emission mode can be adjusted according to the actual needs of the user, thereby improving the skin care effect of the skin care device.

[0036] In addition, since the light source 22 is the main heat source of the skin care device, as the number of light sources 22 increases, the heat at the light source assembly 200 also increases significantly. Compared with clamping the circuit board 300 between the side of the reflective component 21 facing away from the light outlet 11 and the heat dissipation assembly 400, the embodiment of the present application sets the circuit board 300 on the other side of the light source 22, so that the distance between the heat dissipation assembly 400 and the light source assembly 200 can be closer, thereby shortening the heat dissipation path, so as to achieve better heat dissipation effect for the light source assembly 200 of multiple light sources 22, thereby avoiding overheating of the light source assembly 200 due to the operation of multiple light sources 22 and causing abnormal operation, thereby improving the skin care effect of the skin care device.

[0037] The shape of the skin care device can be various, such as a hair dryer type, a long strip type, a flat small rectangle, a circle or an ellipse, etc.; but for (approximately) long strip-shaped skin care devices, the first direction H1 can be the length direction of the skin care device, and the second direction H2 can be the thickness direction of the skin care device, or the first direction H1 can be the length direction of the skin care device, and the second direction H2 can be the width direction of the skin care device, or the first direction H1 can be the width direction of the skin care device, and the second direction H2 can be the thickness direction of the skin care device. The embodiments of the present application do not limit this.

[0038] In the following text, the present application will be mainly described using an (approximately) long strip of skin care equipment as an example. That is, the present application embodiment will continue to use the example that the first direction H1 can be the length direction of the skin care equipment and the second direction H2 can be the thickness direction of the skin care equipment to explain and illustrate the technical solution of the present application embodiment.

[0039] The following describes the technical solutions of the embodiments of the present application using some optional installation structures of the light source assembly 200 as examples.

[0040] In some embodiments, the skin care device may further include a conductive bracket 500. The conductive bracket 500 is mounted on the circuit board 300 and connected to the light source 22, so that the light source 22 is supported on the circuit board 300 and electrically connected to the circuit board 300. Furthermore, the conductive bracket 500 can both mechanically secure the light source 22 to the circuit board 300 and electrically connect the light source 22 to the circuit board 300.

[0041] The conductive bracket 500 can be made of a conductive metal material, such as copper, aluminum, silver, gold, nickel, etc.; the conductive bracket 500 can also be made of some other non-metallic conductive materials such as graphite, conductive rubber, etc., which is not limited in the embodiments of the present application.

[0042] In some embodiments, there are multiple conductive brackets 500 , and ends of all conductive brackets 500 connected to the circuit board 300 are located on the same side of the light source assembly 200 along the second direction H2 .

[0043] For example, there can be only one circuit board 300, located on the first side of the light source assembly 200 along the second direction H2. For example, one circuit board 300 can be located on the upper or lower side of the light source assembly 200 along the thickness direction of the skin care device. This allows all conductive brackets 500 to have their lower ends connected to the light source and their upper ends connected to the circuit board 300 located above the light source assembly 200, or all conductive brackets 500 to have their upper ends connected to the light source and their lower ends connected to the circuit board 300 located below the light source assembly 200. This reduces the number of circuit boards 300 required to install the light source 22 in the skin care device and makes installation of the circuit board 300 within the skin care device more convenient.

[0044] Of course, when there can be multiple circuit boards 300, different circuit boards 300 are located on different sides of the light source assembly 200 along the second direction H2. At this time, all conductive brackets 500 are connected to the first side of the light source assembly 200 along the second direction H2 or the circuit boards on the same side. The embodiment of the present application does not limit this.

[0045] Alternatively, there may be a plurality of conductive brackets 500 , and the ends of all the conductive brackets 500 connected to the circuit board 300 are located on different sides of the light source assembly 200 along the second direction H2 .

[0046] For example, referring to Figure 3, which illustrates a second structural schematic diagram of the circuit board of the skin care device shown in Figure 1, the circuit board 300 may include a first sub-circuit board 31 and a second sub-circuit board 32. The first sub-circuit board 31 and the second sub-circuit board 32 are located on different sides of the light source assembly 200 along the second direction H2. For example, the first sub-circuit board 31 is located on the upper side of the light source assembly 200 along the thickness direction, while the second sub-circuit board 32 is located on the lower side of the light source assembly 200 along the thickness direction.

[0047] Then, during the actual installation process, different conductive brackets 500 can be dispersedly installed on different circuit boards 300 to prevent the conductive brackets 500 from being too densely packed and causing short circuits, leakage, etc. Alternatively, the conductive brackets 500 of different light sources 22 can be conveniently installed on closer circuit boards 300.

[0048] Of course, the circuit board 300 may also be a flexible printed circuit board (FPC), and the flexible printed circuit board 300 may at least partially surround the light source assembly 200. For example, the flexible printed circuit board 300 surrounds the upper side in the thickness direction, the left side in the width direction, and the lower side in the thickness direction of the light source assembly 200, so that part of the conductive bracket 500 is connected to the upper half of the flexible printed circuit board 300 and part of the conductive bracket 500 is connected to the lower half of the conductive bracket 500.

[0049] The conductive bracket 500 of the embodiment of the present application will be described below with reference to the light source 22 .

[0050] The at least two light sources 22 may include a first light source 221 and a second light source 222. Therefore, at least three different light emission modes can be achieved by the first light source 221 and the second light source 222. Of course, the number of light sources 22 may also be three, four, five, or six, and the first light source 221 and the second light source 222 may be any two of the plurality of light sources 22, which is not limited in this embodiment of the present application.

[0051] Please continue to refer to Figure 4, which is a schematic diagram of a second structural embodiment of the conductive support of the skin care device shown in Figure 1. The conductive support 500 includes a first conductive support 51, a second conductive support 52, and a third conductive support 53. The positive electrodes of the first light source 221 and the second light source 222 are both electrically connected to the third conductive support 53. The negative electrode of the first light source 221 is electrically connected to the first conductive support 51, and the negative electrode of the second light source 222 is electrically connected to the second conductive support 52.

[0052] Then, the third conductive bracket 53 can also be understood as a common positive pole, thereby reducing the number of conductive brackets 500 required between the light source 22 and the circuit board 300, so as to simplify the structure of the skin care device and reduce the assembly difficulty and production cost of the skin care device.

[0053] Here, it can also be understood that the circuit board 300, the third conductive bracket 53, the first light source 221 and the first conductive bracket 51 form a first loop, and the circuit board 300, the third conductive bracket 53, the second light source 222 and the second conductive bracket 52 form a second loop. Then, by setting a switch at the corresponding position of the first conductive bracket 51 and another switch at the corresponding position of the second conductive bracket 52, independent control of the first light source 221 and the second light source 222 can be achieved.

[0054] Alternatively, the conductive support 500 may include a first conductive support 51, a second conductive support 52, and a third conductive support 53. The cathodes of the first light source 221 and the second light source 222 are both electrically connected to the third conductive support 53, the anode of the first light source 221 is electrically connected to the first conductive support 51, and the anode of the second light source 222 is electrically connected to the second conductive support 52.

[0055] Then, the third conductive bracket 53 can also be understood as a common negative pole, thereby reducing the number of conductive brackets 500 required between the light source 22 and the circuit board 300, so as to simplify the structure of the skin care device and reduce the assembly difficulty and production cost of the skin care device.

[0056] Here, it can also be understood that the circuit board 300, the third conductive bracket 53, the first light source 221 and the first conductive bracket 51 form a first loop, and the circuit board 300, the third conductive bracket 53, the second light source 222 and the second conductive bracket 52 form a second loop. Then, by setting a switch at the corresponding position of the first conductive bracket 51 and another switch at the corresponding position of the second conductive bracket 52, independent control of the first light source 221 and the second light source 222 can be achieved.

[0057] Of course, in some other embodiments, there are multiple conductive brackets 500. Different light sources 22 are mounted on the circuit board 300 via different conductive brackets 500. This ensures that even if any conductive bracket 500 falls off or is damaged, the remaining conductive brackets 500 can still provide power to the corresponding light source 22, ensuring that the other light sources 22 of the skin care device can function normally. Furthermore, this arrangement can increase light output power (e.g., hair removal power) and / or light output function diversity (e.g., hair removal function diversity). That is, by providing at least two light sources 22, each mounted and fixed to the circuit board 300 via different conductive brackets 500, when hair removal power is required, multiple light sources 22 can be activated simultaneously, while when not required, only one light source 22 can be activated. Alternatively, at least two of the at least two light sources 22 can be configured to alternately illuminate, thereby increasing light output power while reducing or not increasing the power loss of a single light source 22.

[0058] It is also understood that in some other embodiments, the positive electrodes of all light sources 22 are connected to the same conductive bracket 500, and the negative electrodes of all light sources 22 are connected to another conductive bracket 500. Thus, all light sources 22 are installed through the same conductive bracket 500, allowing the light source assembly 200 to operate at a higher maximum power. At the same time, since all light sources 22 are electrically connected through the same conductive bracket 500, the current transmission of all light sources 22 can be more consistent, thereby making the brightness of all light sources 22 more consistent, and ultimately making the brightness at the light outlet 11 more uniform.

[0059] Continuing with the example of a plurality of conductive brackets 500, the spacing between two adjacent conductive brackets 500 is greater than or equal to 0.8 mm and less than or equal to 10 mm. This prevents leakage caused by a small spacing between two adjacent conductive brackets 500, and also prevents excessive space wasted on the skin care device due to a large spacing between two adjacent conductive brackets 500.

[0060] For example, the spacing between two adjacent conductive brackets 500 configured to support different light sources 22 can be 0.8 mm, 0.97 mm, 1.44 mm, 1.98 mm, 2.12 mm, 2.76 mm, 3.11 mm, 3.94 mm, 4.37 mm, 5.44 mm, 6.98 mm, 7.22 mm, 8.73 mm, 9.14 mm or 10 mm, which is not limited to this embodiment of the present application.

[0061] The conductive bracket 500 is described below by way of example in combination with at least two light sources 22 and the reflective component 21 .

[0062] The multiple light sources 22 can be parallel to each other. For example, each light source 22 can include a lamp tube, such as a xenon lamp tube. Each lamp tube can be arranged to extend along the third direction H3, or the length of each lamp tube can be parallel to the third direction H3. The first direction H1, the second direction H2, and the third direction H3 are perpendicular to each other.

[0063] It is understandable that, compared to a scattered and disordered arrangement of multiple light sources 22, the embodiment of the present application can achieve more uniform illumination of the overall light source 22 by arranging the multiple light sources 22 in parallel. Then, taking the skin care device as an example, such as a hair removal device or a skin rejuvenation device, the brightness of light at each position of the light outlet 11 is more uniform, thereby preventing partial areas of the skin from being partially depilated or rejuvenated due to low brightness, thereby improving the effect of hair removal or rejuvenating.

[0064] Continuing with the fact that the first direction H1 can be the length direction of the skin care device and the second direction H2 can be the thickness direction of the skin care device, the third direction H3 can be the width direction of the skin care device. Of course, the specific directions of the first direction H1, the second direction H2, and the third direction H3 can all vary depending on the shape of the skin care device housing 100, and this embodiment of the present application does not limit this.

[0065] In some embodiments, the distances between the multiple light sources 22 and the light outlet 11 can be the same. It is understood that the intensity of the light emitted by the light source 22 decreases as the radiation distance increases. However, by making the distances between the multiple light sources 22 and the light outlet 11 the same in this embodiment of the present application, the brightness of the light at each position of the light outlet 11 can be made more uniform. Continuing with the example of a skin care device being a hair removal device or a skin rejuvenation device, this can avoid incomplete hair removal or skin rejuvenation in some areas of the skin due to weak brightness, thereby improving the hair removal or skin rejuvenation effect.

[0066] It can also be understood that the multiple light sources 22 may be parallel to each other and the distance between each light source 22 and the light outlet 11 may be different; the multiple light sources 22 may be non-parallel to each other and the distance between each light source 22 and the light outlet 11 may be the same; or the multiple light sources 22 may be parallel to each other and the distance between each light source 22 and the light outlet 11 may be the same. The embodiments of the present application do not limit this.

[0067] For example, please continue to refer to Figure 5, which is a schematic diagram of the position of the light source of the skin care device shown in Figure 1. Continuing to combine at least two light sources 22 includes a first light source 221 and a second light source 222. The distance from the first light source 221 to the light outlet 11 is greater than the distance from the second light source 222 to the light outlet 11. In other words, the first light source 221 is closer to the light outlet 11. Then, the power of the first light source 221 can be greater than the power of the second light source 222. As a result, the difference between the intensity of the light radiated from the first light source 221 to the light outlet 11 and the intensity radiated from the second light source 222 to the light outlet 11 is smaller or even approaches the same, so that the brightness of each position at the light outlet 11 is more uniform.

[0068] Next, the position arrangement of the plurality of light sources 22 will be described with reference to the reflective component 21 .

[0069] The reflective component 21 may be provided with a reflective cavity. The reflective cavity opens toward the light outlet 11. At least two light sources 22 are mounted within the reflective cavity. Thus, the reflective cavity can converge light emitted by the light sources 22 in a 360-degree divergent pattern toward the light outlet 11 through reflection, thereby increasing the light output efficiency of the light source assembly 200 or, in other words, improving the brightness at the light outlet 11.

[0070] At least two light sources 22 may be spaced apart in the second direction H2.

[0071] For example, we can continue to combine the above-mentioned distances between each light source 22 and the light outlet 11, and / or each light source 22 is parallel to each other; then, the two light sources 22 can be staggered up and down in the thickness direction of the skin care device, and are both extended along the width direction of the skin care device, so that the brightness at each position at the light outlet 11 is more uniform.

[0072] Please continue to refer to Figure 6, which illustrates another schematic diagram of the positions of the light sources of the skin care device shown in Figure 1. In some embodiments, along the second direction H2, the reflective cavity is symmetrical about the first axis L1, which is parallel to the first direction H1, and all light sources 22 are arranged symmetrically about the first axis L1. Since the reflective cavity is symmetrical about the first axis L1, when the light sources 22 are arranged symmetrically about the first axis L1, the light reflected by the inner wall of the reflective cavity from the multiple light sources 22 can be more uniform.

[0073] In some embodiments, the reflective component 21 may include a first straight portion 211, a connecting portion 212, and a second straight portion 213 connected in sequence. The first straight portion 211 and the second straight portion 213 are spaced apart along the second direction H2, with the connecting portion 212 facing the light outlet 11, so that the first straight portion 211, the connecting portion 212, and the second straight portion 213 enclose a reflective cavity with an opening facing the light outlet 11. Thus, a portion of the light emitted by the light source 22 can be emitted directly from between the first straight portion 211 and the second straight portion 213 toward the light outlet 11, and another portion of the light emitted by the light source 22 can be emitted toward the light outlet 11 after being reflected by one or more of the connecting portion 212, the first straight portion 211, and the second straight portion 213.

[0074] In some embodiments, the connecting portion 212 includes a curved surface. One end of the curved surface in the circumferential direction is connected to the first straight portion 211. The other end of the curved surface in the circumferential direction is connected to the second straight portion 213. Alternatively, it can be simply understood that the first straight portion 211, the second straight portion 213 and the connecting portion 212 are in a U-shaped structure, and the connecting portion 212 is located in the middle of the U-shaped structure. Then, since the connecting portion 212 is in the shape of a parabola, it can have a good focusing effect on the light radiated by the multiple light sources 22, thereby improving the brightness at the light outlet 11 and making the brightness at each location at the light outlet 11 more uniform.

[0075] Alternatively, please continue to refer to Figure 7, which is a schematic diagram of a second structural embodiment of the reflective component of the skin care device shown in Figure 1. The connecting portion 212 may further include at least two light-collecting curved surfaces 2121, each of which is provided in correspondence with a light source 22, so that each light-collecting curved surface 2121 provides a good light-collecting effect for the corresponding light source 22. This embodiment of the present application is not limited to this.

[0076] In some embodiments, the connecting portion 212 surrounds at least two light sources 22. One end of the connecting portion 212 connected to the first straight portion 211 and one end of the connecting portion 212 connected to the second straight portion 213 both protrude from a side of the at least two light sources 22 close to the light outlet 11.

[0077] Alternatively, it can be simply understood that along the first direction H1, the multiple light sources 22 are all located on the inner side of the connecting portion 212, so that the connecting portion 212 can provide a better focusing effect for the multiple light sources 22 and improve the uniformity of brightness at various positions at the light outlet 11.

[0078] It is understandable that the light source 22 may be completely located in the space enclosed by the connecting portion 212 , or may be only partially located in the space enclosed by the connecting portion 212 , and this embodiment of the present application does not limit this.

[0079] For example, please refer to Figure 8, which is a schematic diagram of the light source structure of the skin care device shown in Figure 2. Continuing with the light source 22 being a lamp tube, the lengthwise direction, first direction H1, and second direction H2 of the lamp tube are perpendicular to each other. At least one end of the lamp tube in the lengthwise direction is located outside the connecting portion 212. Along the lengthwise direction of the lamp tube, the length of each end of the lamp tube outside the connecting portion 212 is less than or equal to one-fifth of the total length of the lamp tube.

[0080] For example, along the length direction of the lamp tube, the length of the portion of each end of the lamp tube outside the connecting portion 212 is one fifth, one sixth, one seventh, one eighth, etc. of the total length of the lamp tube, which is not limited in this embodiment of the present application.

[0081] It is understandable that the brightness of the two ends of the lamp tube along the length direction is usually lower when the lamp tube is working. Therefore, setting the lower brightness part of the lamp tube to the outside of the reflective component 21 will not cause excessive waste of the light emitted by the lamp tube, and can also make the pin of the lamp tube located on the outside of the connecting part 212 to facilitate connection with the conductive bracket 500, thereby reducing the difficulty of assembly and production of the skin care device.

[0082] Please continue to refer to Figure 9, which is a schematic diagram of the structure of the light source shown in Figure 8 after the isolation member is installed. In some embodiments, the skin care device also includes a conductive bracket 500, which can be installed on the circuit board 300 and connected to the light source 22, so that the light source 22 is supported by the circuit board 300 and located in the reflective cavity and electrically connected to the circuit board 300. In addition, the light source 22 can be a lamp tube, each light source 22 is arranged near the inner wall of the reflective cavity, and the reflective component 21 is electrically connected to the circuit board 300 so that the circuit board 300 can excite or trigger the lamp tube through the reflective component 21. Then, the skin care device can also include an isolation member 23. The isolation member 23 is arranged outside at least two light sources 22 and separates the reflective component 21 from the conductive bracket 500. Thereby, it is possible to prevent the reflective component 21 and the conductive bracket 500 from contacting each other to form a short circuit or leakage.

[0083] Of course, the skin care device can also include a conductive bracket 500, which can be installed on the circuit board 300 and connected to the light source 22, so that the light source 22 is supported on the circuit board 300 and is located in the reflective cavity and electrically connected to the circuit board 300. In addition, the light source 22 can be a lamp tube, and each light source 22 is arranged close to the inner wall of the reflective cavity. The reflective component 21 is electrically connected to the circuit board 300 so that the circuit board 300 can excite or trigger the lamp tube through the reflective component 21. Then, at this time, the skin care device can also include an isolator 23. The isolator 23 is sleeved on the outside of the conductive bracket 500, and the isolator 23 separates the reflective component 21 and the conductive bracket 500. Thereby, it is possible to avoid the reflective component 21 and the conductive bracket 500 from contacting each other to form a short circuit or leakage.

[0084] In some embodiments, the light source 22 is continued to be a lamp tube. When at least one end of the lamp tube in the length direction is located at the connecting portion 212 or located outside the reflective component 21, the portion of the lamp tube located outside the connecting portion 212 can be provided with an isolation member 23; or, the isolation member 23 can be provided outside the conductive bracket 500.

[0085] Next, the conductive bracket 500 may be located outside the reflective cavity or may be disposed through the reflective component 21 for illustration.

[0086] In some embodiments, one end of at least one light source 22 is located outside the reflective cavity and connected to the conductive bracket 500. The skin care device may also include an isolation member 23, which is mounted outside the light source 22 and located between the reflective component 21 and the conductive bracket 500, thereby separating the reflective component 21 and the conductive bracket 500.

[0087] In some embodiments, a through hole communicating with the reflective cavity is provided on the reflective component 21, and at least one conductive bracket 500 is passed through the reflective cavity through the through hole and connected to the light source 22. The skin care device may further include an isolating member 23, which is sleeved on the outside of the conductive bracket 500 and located in the through hole, thereby separating the reflective component 21 and the conductive bracket 500.

[0088] For example, continuing to combine the light source 22 as a lamp tube, when the conductive bracket 500 passes through the reflective component 21 and extends into the reflective cavity to support the light source 22, an isolation member 23 is disposed outside the conductive bracket 500, and the isolation member 23 is at least partially located in the hole through which the reflective component 21 is penetrated.

[0089] In this way, the isolation member 23 is configured to separate the reflective component 21 and the conductive bracket 500 to isolate the reflective component 21 and the conductive bracket 500 to prevent the reflective component 21 from leaking electricity to the conductive bracket 500 or the conductive bracket 500 from leaking electricity to the reflective component 21, thereby providing safety in use.

[0090] The spacer 23 is sleeved outside the at least two light sources 22 , which has at least the following two meanings.

[0091] The ends of multiple lamps on the same side may all be inserted into the same isolation member 23. For example, among multiple lamps that cooperate with the same isolation member 23, different lamps may be inserted into different isolation holes of the isolation member 23 to achieve isolation. Alternatively, different lamps may be separated by different isolation members 23, which is not limited in this embodiment of the present application.

[0092] The isolation member 23 is sleeved outside the conductive bracket 500, which has at least the following two meanings.

[0093] Adjacent conductive brackets 500 may all be inserted into the same isolation member 23. For example, among multiple conductive brackets 500 that cooperate with the same isolation member 23, different conductive brackets 500 may be inserted into different isolation holes of the isolation member 23 to achieve isolation. Alternatively, different conductive brackets 500 may be separated by different isolation members 23, which is not limited in this embodiment of the present application.

[0094] It is also understandable that the isolating member 23 may be made of an insulating material, such as rubber. Of course, the isolating member 23 may also be made of other insulating materials such as ceramics, which is not limited in this embodiment of the present application.

[0095] For example, the skin care device also includes a conductive bracket 500, which is installed on the circuit board 300. One end of at least one light source 22 is located outside the reflective cavity and is electrically connected to the conductive bracket 500, so that the conductive bracket 500 is electrically connected to the circuit board 300.

[0096] Each end of each light source 22 in the length direction may be located outside the reflective cavity such as the connecting portion 212, or each end of an individual light source 22 in the length direction may be located outside the reflective cavity such as the connecting portion 212. This embodiment of the application does not limit this.

[0097] Alternatively, please continue to refer to Figure 10, which is a schematic diagram of a third structural embodiment of the conductive bracket of the skin care device shown in Figure 1. The skin care device may further include a conductive bracket 500, which is mounted on the circuit board 300 and connected to the light source 22, thereby electrically connecting the conductive bracket 500 to the circuit board 300; at least one conductive bracket 500 is disposed through the reflective component 21, such as through the connecting portion 212.

[0098] When at least one end of the lamp tube along the length direction is located in the reflective cavity, the end of the lamp tube located in the reflective cavity is installed through the conductive bracket 500 that passes through the reflective component 21.

[0099] In some embodiments, the light source 22 may abut the reflective component 21, such as the connecting portion 212 of the reflective component 21, thereby reducing the gap between the light source 22 and the reflective component 21. This further makes the light source assembly 200 more compact, facilitating miniaturization of the skin care device.

[0100] Continuing with the light source 22, which may be a lamp tube, when the size of the space in the connecting portion 212 is certain, the light source 22 directly abuts against the connecting portion 212, and the distance between the first light source 221 and the second light source 222 can be made larger, thereby reducing the probability of mutual interference between the first light source 221 and the second light source 222, so as to improve the reliability of the light source 22; in other words, it is possible to set the first light source 221 and the second light source 222 in the reflective component 21 without increasing or slightly increasing the reflective component 21, thereby facilitating a miniaturized design.

[0101] For example, when the at least two light sources 22 include a first light source 221 and a second light source 222 , and the connecting portion 212 of the reflective component 21 includes an arcuate surface, the first light source 221 and the second light source 222 can be respectively disposed at two trisection points of the connecting portion 212 .

[0102] When the number of the light sources 22 is greater than three, the multiple light sources 22 may be arranged along the inner wall surface of the reflection cavity.

[0103] For example, when the number of light sources 22 is three and the connecting portion 212 of the reflective component 21 includes a curved surface, the three light sources 22 are respectively located at three quarter-divided points of the connecting portion 212; when the number of light sources 22 is four and the connecting portion 212 of the reflective component 21 includes a curved surface, the four light sources 22 are respectively located at four fifth-divided points of the connecting portion 212.

[0104] Continuing with the light source 22 being a lamp, the reflective member 21 can be electrically connected to the circuit board 300, allowing the circuit board 300 to excite (i.e., trigger) the lamp via the reflective member 21. Furthermore, it can also be understood that the reflective member 21 can be reused to excite the lamp, eliminating the need to wrap a wire (e.g., a filament) around the surface of the lamp to excite it. This further simplifies the structure of the skin care device, reducing the difficulty and cost of manufacturing the skin care device.

[0105] Of course, in other embodiments, when the light source 22 is at a greater distance from the reflective component 21 , the light source can also be triggered by wrapping a filament around the light source 22 , and this embodiment of the present application does not limit this.

[0106] If the light source 22 is a lamp tube, all the lamp tubes may have the same length, so that the brightness of the light emitted by different light sources 22 is more consistent, and the brightness at each position of the light port 11 is more uniform.

[0107] The above is an example of some optional structures for the position arrangement of at least two light sources 22 in the embodiment of the present application. Next, the technical solution of the embodiment of the present application will be explained and illustrated in combination with some optional structures of the conductive bracket 500.

[0108] 11 is a schematic diagram illustrating the structure of the conductive support of the skin care device shown in FIG2. Continuing with the example of at least two light sources 22 including a first light source 221 and a second light source 222, the circuit board 300, the first light source 221, and the second light source 222 may be sequentially arranged along the second direction H2.

[0109] In this case, the skin care device may further include a first conductive bracket 51 and a second conductive bracket 52, which are the conductive bracket 500 described above. The first conductive bracket 51 is connected between the first light source 221 and the circuit board 300. The second conductive bracket 52 includes a first portion 521 and a second portion 522 that are connected in a bent manner. The first portion 521 is connected to the circuit board 300. The first portion 521 is spaced apart from the first conductive bracket 51 along the first direction H1 and / or the third direction H3, with the first direction H1, the second direction H2, and the third direction H3 being perpendicular to each other. The second portion 522 is spaced apart from the first conductive bracket 51 along the second direction H2 and is connected to the second light source 222.

[0110] In this way, at least two light sources 22 can be set with equal length, can be individually mounted on the same circuit board 300, and supported in the reflective cavity, thereby achieving flexible control of the at least two light sources 22 to increase the light output power (such as hair removal power) and / or the diversity of light output functions.

[0111] For example, if the circuit board 300, the first light source 221, and the second light source 222 are arranged sequentially from top to bottom along the thickness direction of the skin care device, the first conductive bracket 51 can be arranged to extend from top to bottom. The first portion 521 of the second conductive bracket 52 can also be arranged to extend from top to bottom, with the first portion 521 and the first conductive bracket 51 spaced apart in the front-to-back or left-to-right direction.

[0112] For example, referring to Figures 11 to 14, Figure 12 is a schematic diagram of the structure of the conductive support shown in Figure 11, Figure 13 is a schematic diagram of a fourth structural embodiment of the conductive support of the skin care device shown in Figure 1, and Figure 14 is a schematic diagram of a fifth structural embodiment of the conductive support of the skin care device shown in Figure 1. The first portion 521 may be located on a side of the first conductive support 51 that is close to or away from the light outlet 11. Of course, the first portion 521 may also be located on a side of the first conductive support 51 along the third direction H3, and this embodiment of the present application is not limited thereto.

[0113] In some embodiments, at least one of the width of the first conductive support 51 and the width of the first portion 521 is equal to the width of the second portion 522. This allows the resistance of each conductive support 500 and / or each conductive support 500 to be substantially the same, thereby making the current transmission between the circuit board 300 and each light source 22 more consistent, thereby achieving more uniform brightness at each position of the light port 11.

[0114] The width of only the first conductive bracket 51 may be equal to the width of the second part 522, or the width of the first part 521 may be equal to the width of the second part 522, or the width of the first conductive bracket 51, the first part 521 and the second part 522 may all be equal. This embodiment of the present application does not limit this.

[0115] In some embodiments, the light sources 22 may be lamp tubes extending along the third direction H3, with the first direction H1, the second direction H2, and the third direction H3 being perpendicular to each other, and all the lamp tubes having the same length in the third direction H3. This allows for more consistent brightness of light emitted by different light sources 22, resulting in more uniform brightness at various locations on the light port 11.

[0116] In some embodiments, each light source 22 is disposed close to the inner wall of the reflective cavity, and the distance between each light source 22 and the inner wall of the reflective cavity is less than or equal to 0.3 mm.

[0117] For example, the distance between the light source 22 and the inner wall of the reflective cavity can be 0.3 mm, 0.287 mm, 0.266 mm, 0.214 mm, 0.201 mm, 0.177 mm, 0.15 mm, 0.123 mm, 0.1 mm, 0.081 mm, 0.05 mm or 0 mm; when the distance between the light source 22 and the inner wall of the reflective cavity is 0 mm, it can also be understood that the light source 22 is in contact with the inner wall of the reflective cavity.

[0118] Of course, please continue to refer to Figure 15, which is a sixth structural diagram of the conductive bracket of the skin care device shown in Figure 1. In some other embodiments, the length of the light source 22 may also be different.

[0119] For example, further combining at least two light sources 22, including a first light source 221 and a second light source 222, the circuit board 300, the first light source 221, and the second light source 222 are arranged sequentially along the second direction H2. The first light source 221 and the second light source 222 are lamp tubes extending along the third direction H3. The first direction H1, the second direction H2, and the third direction H3 are perpendicular to each other, and each end of the second light source 222 protrudes from the first light source 221 along the third direction H3. In this case, the skin care device may further include a first conductive bracket 51 and a second conductive bracket 52. The first conductive bracket 51 is connected between the first light source 221 and the circuit board 300. The second conductive bracket 52 is connected between the second light source 222 and the circuit board 300, and the second conductive bracket 52 is spaced apart from the first conductive bracket 51 along the third direction H3. Of course, it can also be simply understood that the second conductive bracket 52 is located on the side of the adjacent first conductive bracket 51 away from the first light source 221, or is located outside the adjacent first conductive bracket 51.

[0120] The above are some examples of when the conductive brackets 500 are all connected to the circuit board 300 on the same side of the light source assembly 200. The following continues to use the example of the conductive brackets 500 being connected to the circuit boards 300 on different sides of the light source assembly 200 to further explain the technical solutions of the embodiments of the present application.

[0121] The light source 22 includes a first light source 221 and a second light source 222 arranged along a second direction H2. The circuit board 300 includes a first sub-circuit board 31 and a second sub-circuit board 32. The first sub-circuit board 31 is located on a side of the first light source 221 facing away from the second light source 222. The second sub-circuit board 32 is located on a side of the second light source 222 facing away from the first light source 221. The skin care device also includes a first conductive bracket 51 and a second conductive bracket 52. The first conductive bracket 51 is connected between the first sub-circuit board 31 and the first light source 221, and the second conductive bracket 52 is connected between the second sub-circuit board 32 and the second light source 222.

[0122] It can be understood that the above designs can make at least two light sources 22 set with equal length and can be supported individually in the reflective cavity, thereby realizing flexible control of at least two light sources 22 to increase the light output power (such as hair removal power) and / or the diversity of light output functions.

[0123] The above are some examples of the light source assembly 200 in the embodiment of the present application. The following will continue with examples in combination with some other optional structures in the embodiment of the present application.

[0124] Continuing with Figures 16 to 18, Figure 16 is a top view of the skin care device shown in Figure 1, Figure 17 is a cross-sectional view of the skin care device shown in Figure 16 along the AA direction, and Figure 18 is an enlarged view of the X in Figure 17. The skin care device further includes a cold compress assembly 600 mounted on the housing 100 for applying a cold compress to the skin.

[0125] For example, the cold compress assembly 600 may include a light guide component 61 and a cooling plate 62. The light guide component 61 is disposed at the light outlet 11 to transmit light emitted by the light source 22. The cooling plate 62 is thermally connected to the light guide component 61; for example, the cooling plate 62 may be directly attached to the light guide component 61 or attached to the light guide component 61 via a thermally conductive medium such as thermal grease.

[0126] Furthermore, the light guide component 61 can be cooled by the cooling sheet 62. The cooled light guide component 61 is exposed from the light outlet 11 so that it can come into contact with the skin, so that the light guide component 61 can not only transmit the light of the light source 22 to care for the user's skin, but also be cooled by the cooling sheet 62 to provide a cold compress for the user.

[0127] Of course, it can also be understood that the light source assembly 200 serves as the main heat source of the skin care device, and the light guide component 61 is located on the light output side of the light source assembly 200. The light guide component 61 is cooled by the cooling plate 62, which can also have a heat dissipation effect on the light source assembly 200 to a certain extent, thereby preventing the light source assembly 200 from being damaged due to excessive temperature.

[0128] The cooling plate 62 is also called a semiconductor cooling plate. It uses the Peltier effect of semiconductor materials. When direct current passes through a galvanic couple composed of two different semiconductor materials connected in series, heat can be absorbed and released at both ends of the galvanic couple respectively, thereby achieving the purpose of cooling.

[0129] The light-guiding component 61 may be made of sapphire or other light-guiding materials, which is not limited in the embodiment of the present application.

[0130] The skin care device may further include a filter 700 , which is disposed between the light source assembly 200 and the light guide member 61 , and is configured to filter the light emitted from the light source assembly 200 to the light guide member 61 .

[0131] For example, filter 700 can be configured to transmit light with wavelengths between 420 and 1200 nanometers, thereby generating IPL (intense pulsed light) to illuminate the user's skin. In actual use, the wavelength required for hair removal may be between 420 and 1200 nanometers, while the wavelength required for skin rejuvenation may be between 600 and 1200 nanometers. This allows the skin care device to simultaneously perform cooling, skin rejuvenation, and hair removal functions.

[0132] Next, the technical solution of the embodiment of the present application will be described with examples in combination with some optional structures of the heat dissipation assembly 400 of the embodiment of the present application.

[0133] The housing 100 may be provided with a heat dissipation channel 12. The heat dissipation assembly 400 includes a fan 41 configured to drive air in the heat dissipation channel 12 to flow in a predetermined direction to dissipate heat for the light source assembly 200 and / or the cold compress assembly 600.

[0134] That is to say, the fan 41 can be configured to dissipate heat only for the light source assembly 200, or only for the cold compress assembly 600, or simultaneously for the light source assembly 200 and the cold compress assembly 600. This embodiment of the present application does not limit this.

[0135] For example, when the heat dissipation component 400 is configured to dissipate heat for the cold compress component 600, the heat dissipation component 400 may further include a heat conductor 42 and a heat sink 43. The heat conductor 42 includes a first end and a second end. The first end is thermally connected to the cooling fin 62; for example, the first end is directly attached to the cooling fin 62 or attached through a heat-conducting medium such as thermal grease. The heat sink 43 is thermally connected to the second end; for example, the first end is directly attached to the cooling fin 62 or attached through a heat-conducting medium such as thermal grease. The heat sink 43 is located on the side of the reflective component 21 facing away from the light outlet 11 and is at least partially located in the heat dissipation channel 12.

[0136] Therefore, after the heat conducting member 42 conducts the heat of the cooling fin 62 to the heat sink 43 , the fan 41 quickly completes the air cooling of the heat sink 43 by driving the air flow in the heat dissipation channel 12 .

[0137] For example, when the heat dissipation assembly 400 is configured to dissipate heat for the light source assembly 200 and the cold compress assembly 600 at the same time, the heat dissipation channel 12 may include a first heat dissipation channel and a second heat dissipation channel.

[0138] The first heat dissipation channel is connected between the air outlet of the housing 100, such as the first air outlet 13, and the fan 41. At least one of the light source 22 and the reflective component 21 is located in the first heat dissipation channel, so that the fan 41 can be used to dissipate heat for the light source 22 and / or the reflective component 21 in the first heat dissipation channel.

[0139] The second heat dissipation channel is connected between the air outlet of the housing 100, such as the second air outlet 14, and the fan 41. The heat sink 43 is located in the second heat dissipation channel, so that the heat conduction member 42 transfers the heat of the cooling fin 62 to the radiator, and then the fan 41 cools the second heat dissipation channel to achieve heat dissipation.

[0140] In some embodiments, the second heat dissipation channel and the first heat dissipation channel can be independent of each other, so that zoned cooling can be achieved inside the skin care device, thereby ensuring good heat dissipation at the light source assembly 200 and the cold compress assembly 600.

[0141] Of course, the second heat dissipation channel and the first heat dissipation channel may also partially intersect, and this embodiment of the present application does not limit this.

[0142] For example, referring to Figure 19, which is a cross-sectional view of the skin care device shown in Figure 16 along the BB direction, the skin care device may further include a mounting bracket 800. Mounting bracket 800 is disposed within housing 100 and defines a first mounting cavity 81, a connecting passage 82, and a second mounting cavity 83.

[0143] The light source 22 and the reflective component 21 are arranged in the first installation cavity 81, one end of the connecting channel 82 is connected to the first installation cavity 81, and the other end of the connecting channel 82 is connected to the air outlet of the fan 41, so that the first installation cavity 81 and the connecting channel 82 form at least part of the first heat dissipation channel.

[0144] The heat sink 43 is at least partially disposed in the second installation cavity 83 . The second installation cavity 83 is communicated with the air outlet of the fan 41 to form at least a portion of a second heat dissipation channel.

[0145] The mounting bracket 800 can be composed of at least two brackets. For example, the mounting bracket 800 includes a first bracket and a second bracket. The first bracket and the second bracket are spliced ​​to form the above-mentioned first mounting cavity 81, connecting channel 82 and second mounting cavity 83, thereby reducing the production difficulty of the mounting bracket 800.

[0146] The mounting bracket 800 may be provided with corresponding slots and ribs inside to facilitate the snap-on connection of the reflective component 21 , the filter 700 , etc., which is not limited in this embodiment of the present application.

[0147] The mounting bracket 800 may also be provided with corresponding openings so that the light guide component 61 and the cooling plate 62 can be passed through the mounting bracket 800 , and this embodiment of the present application does not limit this.

[0148] The fan 41 can be a centrifugal fan, an axial flow fan, a cross flow fan, etc., and this embodiment of the present application does not limit this.

[0149] For example, when the fan 41 is a centrifugal fan, the air inlet of the volute of the centrifugal fan is connected to the air outlet of the outer casing 100, such as the third air outlet 15, and the inlet of the connecting channel 82 and the inlet of the second installation cavity 83 are arranged side by side at the air outlet of the volute of the centrifugal fan, so that the centrifugal fan can drive the air outside the outer casing 100 into the volute of the centrifugal fan, and then be divided into two paths from the volute of the centrifugal fan, one path is discharged after passing through the connecting channel 82 and the first installation cavity 81 to cool the light source 22 and / or the reflective component 21, and the other path passes through the second installation cavity 83 to cool the heat sink 43 or the cold compress component 600.

[0150] In some embodiments, the heat sink 43 may include a plurality of fins. The fins are protruding from one side of the second end along the second direction H2 and are located within the heat dissipation channel 12. The fan 41 is located on a side of the fins along the first direction H1 that faces away from the reflective component 21. The height of the fins in the second direction H2 is greater than or equal to the height of the light source assembly 200 in the second direction H2.

[0151] It can be understood that, compared with the fan 41 and the fins arranged along the second direction H2 behind the light source assembly 200, the embodiment of the present application can be understood as moving the fan 41 in the direction away from the light source assembly 200, so that the fins can be made larger in the second direction H2 to increase the contact area between the heat sink 43 and the air, thereby greatly improving the heat dissipation effect of the heat sink 43.
