[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, which results in poor skin care effects of the skin care device. Utility Model Content

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] Hair removal devices, photorejuvenation devices, etc. are commonly used skin care devices in people's lives. These skin care devices mainly irradiate the user's skin with IPL (intense pulsed light), thereby achieving effects such as hair removal and photorejuvenation on the user's skin.

[0044] 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, which results in poor skin care effects of the skin care device.

[0045] Based on this, the embodiment of the present application provides a skin care device to improve the skin care effect. Specifically, the skin care device can be a hair removal device or a skin rejuvenation device, etc., to remove hair or rejuvenate the skin. Of course, the skin care device can also be some beauty devices with hair removal or skin rejuvenation functions, which are not limited in the embodiment of the present application.

[0046] Please refer to Figure 1 and Figure 2 , Figure 1 A three-dimensional diagram of a skin care device provided in an embodiment of the present application, Figure 2 for Figure 1 The skin care device may include a housing 100 , a light source assembly 200 , a circuit board 300 and a heat dissipation assembly 400 .

[0047] 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 of 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.

[0048] It is understandable that the embodiment 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, multiple light sources 22 can be switched 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; or 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 as to adjust to a more suitable light emission mode according to the actual needs of the user, thereby improving the skin care effect of the skin care device.

[0049] Furthermore, 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 the multiple light sources 22, thereby avoiding overheating of the light source assembly 200 due to the operation of the multiple light sources 22 and causing abnormal operation, thereby further improving the skin care effect of the skin care device.

[0050] Among them, the shape of the skin care device can be various, such as a hair dryer type, a long strip shape, a flat small rectangle or a circle or an ellipse, etc.; but for (approximately) long strip 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.

[0051] In the following text, the present application is mainly explained by taking the (approximately) long strip-shaped skin care device as an example. That is, the embodiment of the present application will continue to take the first direction H1 as the length direction of the skin care device and the second direction H2 as the thickness direction of the skin care device as an example to further explain and illustrate the technical scheme of the embodiment of the present application.

[0052] The following is an illustrative description of the technical solution of the embodiment of the present application using some optional installation structures of the light source assembly 200.

[0053] 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 be used to mechanically connect and fix the light source 22 to the circuit board 300, and can also be electrically connected to the circuit board 300.

[0054] Specifically, 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 some other non-metallic conductive materials such as graphite, conductive rubber, etc., which is not limited in the embodiments of the present application.

[0055] 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 .

[0056] For example, there may be only one circuit board 300, and the circuit board 300 is located at the first side of the light source assembly 200 along the second direction H2. For example, the circuit board 300 is located at the upper side or the lower side of the light source assembly 200 along the thickness direction of the skin care device, so that the lower ends of all the conductive brackets 500 are connected to the light source, and the upper ends are connected to the circuit board 300 located at the upper side of the light source assembly 200, or the upper ends of all the conductive brackets 500 are connected to the light source, and the lower ends are connected to the circuit board 300 located at the lower side of the light source assembly 200. Thus, the number of circuit boards 300 required for installing the light source 22 in the skin care device can be reduced, and the installation of the circuit board 300 inside the skin care device is more convenient.

[0057] 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 circuit boards on the first side or the same side of the light source assembly 200 along the second direction H2. The embodiment of the present application does not limit this.

[0058] Alternatively, there may be a plurality of conductive brackets 500 , and ends of all conductive brackets 500 connected to the circuit board 300 are located at different sides of the light source assembly 200 along the second direction H2 .

[0059] For example, please continue to refer to Figure 3 , Figure 3 for Figure 1 A second structural schematic diagram of a circuit board of a skin care device is shown. 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 respectively 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, and the second sub-circuit board 32 is located on the lower side of the light source assembly 200 along the thickness direction.

[0060] Then, in the actual installation process, different conductive brackets 500 can be dispersedly installed on different circuit boards 300 to prevent short circuits, leakage, etc. caused by too dense conductive brackets 500. Alternatively, conductive brackets 500 of different light sources 22 can be installed on closer circuit boards 300.

[0061] Of course, the circuit board 300 may also be a flexible circuit board (FPC), and the flexible circuit board 300 may at least partially surround the light source assembly 200. For example, the flexible 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 circuit board 300, and part of the conductive bracket 500 is connected to the lower half of the conductive bracket 500.

[0062] The above is an example description of some optional structures of the conductive bracket 500 in the embodiment of the present application based on the different numbers and shapes of the circuit boards 300. The conductive bracket 500 in the embodiment of the present application will be described below with examples in combination with the optional structure of the light source 22.

[0063] 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 may be realized by the first light source 221 and the second light source 222. Of course, the number of the 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 the embodiments of the present application.

[0064] Please continue to refer to Figure 4 , Figure 4 for Figure 1 A second structural schematic diagram of a conductive support of a skin care device is shown. 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.

[0065] Then, the third conductive bracket 53 can also be understood as a common positive electrode, 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.

[0066] 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. Therefore, 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.

[0067] 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.

[0068] Then, the third conductive bracket 53 can also be understood as a common negative electrode, 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.

[0069] 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. Therefore, 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.

[0070] Of course, in some other embodiments, the number of the conductive brackets 500 is multiple. Different light sources 22 are mounted on the circuit board 300 through different conductive brackets 500. Therefore, after any conductive bracket 500 falls off or is damaged, the remaining conductive brackets 500 can also supply power to the corresponding light source 22 to ensure that the other light sources 22 of the skin care device can work normally. More importantly, such a setting can increase the light output power (such as hair removal power) and / or the diversity of light output functions (such as hair removal function diversity), that is, by setting at least two light sources 22, and the at least two light sources 22 are respectively mounted and fixed on the circuit board 300 through different conductive brackets 500, when the hair removal power needs to be increased, multiple light sources 22 can be turned on at the same time, and when it is not needed, one of the light sources 22 can be turned on; or at least two lamps in the at least two light sources 22 can be alternately illuminated, so as to increase the light output power while reducing or not increasing the loss of a single light source 22.

[0071] It can also be understood that in some other embodiments, the positive electrodes of all the light sources 22 can be connected to the same conductive bracket 500, and the negative electrodes of all the light sources 22 can be connected to another conductive bracket 500, so that all the light sources 22 are installed through the same conductive bracket 500, so that the light source assembly 200 can work at a higher maximum power. At the same time, since all the light sources 22 are electrically connected through the same conductive bracket 500, the current transmission of all the light sources 22 can be made more consistent, so that the brightness of all the light sources 22 is more consistent, and finally the brightness at the light outlet 11 is made more uniform.

[0072] Taking the example of the number of conductive brackets 500 being multiple, the distance between two adjacent conductive brackets 500 is greater than or equal to 0.8 mm and less than or equal to 10 mm. This can avoid leakage caused by too small a distance between two adjacent conductive brackets 500, and can also avoid wasting too much space of the skin care device due to too large a distance between two adjacent conductive brackets 500.

[0073] For example, the spacing between two adjacent conductive brackets 500 for supporting 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.

[0074] The above is an example of some overall position layouts of multiple conductive brackets 500 in the embodiment of the present application. The following continues to illustrate the conductive bracket 500 with examples in combination with some optional position arrangements of at least two light sources 22 and some optional structures of the reflective component 21.

[0075] The multiple light sources 22 may be parallel to each other. For example, each light source 22 may include a lamp tube such as a xenon lamp tube, and each lamp tube may be arranged to extend along the third direction H3, or the length direction of each lamp tube is parallel to the third direction H3. The first direction H1, the second direction H2 and the third direction H3 are perpendicular to each other.

[0076] It is understandable that, compared with the scattered and disordered arrangement of multiple light sources 22, the embodiment of the present application can make the overall light emission formed by the multiple light sources 22 more uniform by making the multiple light sources 22 parallel to each other. Then, taking the skin care device as an example, which is 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 avoiding the situation where hair removal or skin rejuvenation is not in place in some areas of the skin due to weak brightness, thereby improving the effect of hair removal or skin rejuvenation.

[0077] Specifically, the first direction H1 can be the length direction of the skin care device, the second direction H2 can be the thickness direction of the skin care device, and the third direction H3 can be the width direction of the skin care device. Of course, according to the shape change of the shell 100 of the skin care device, the specific directions of the first direction H1, the second direction H2 and the third direction H3 can all be changed, and the embodiment of the present application does not limit this.

[0078] In some embodiments, the distances from the multiple light sources 22 to the light outlet 11 may be the same. It is understandable that the light intensity of the light emitted by the light source 22 will decrease as the radiation distance increases, and the embodiment of the present application makes the distances from the multiple light sources 22 to the light outlet 11 the same, so that the brightness of the light at each position of the light outlet 11 can be more uniform. Then, taking the skin care device as a hair removal device or a skin rejuvenation device as an example, it can avoid the situation where the hair removal or skin rejuvenation of some areas of the skin is incomplete due to weak brightness, so as to improve the effect of hair removal or skin rejuvenation.

[0079] It can also be understood that the multiple light sources 22 may be parallel to each other and the distance from each light source 22 to the light outlet 11 may be different; the multiple light sources 22 may be non-parallel to each other and the distance from each light source 22 to the light outlet 11 may be the same; or the multiple light sources 22 may be parallel to each other and the distance from each light source 22 to the light outlet 11 may be the same. The embodiments of the present application are not limited to this.

[0080] For example, please continue to refer to Figure 5 , Figure 5 for Figure 1 A schematic diagram of the position of the light source of the skin care device shown. Continuing to combine at least two light sources 22 including 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 may 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.

[0081] Next, the position arrangement of the plurality of light sources 22 will be described with examples in combination with some optional structures of the reflective component 21 .

[0082] The reflective component 21 may be provided with a reflective cavity. The opening of the reflective cavity faces the light outlet 11. At least two light sources 22 are installed in the reflective cavity. Thus, the light emitted by the light source 22 in a 360° manner can be converged to the light outlet 11 by reflection through the reflective cavity, so as to improve the light extraction rate of the light source assembly 200 or the brightness at the light outlet 11.

[0083] At least two light sources 22 may be spaced apart from each other in the second direction H2.

[0084] For example, the distance between each light source 22 and the light outlet 11 can be the same, and / or each light source 22 can be parallel to each other; then, the two light sources 22 can be offset up and down in the thickness direction of the skin care device, and can be extended along the width direction of the skin care device, so that the brightness at each position of the light outlet 11 is more uniform.

[0085] Please continue to refer to Figure 6 , Figure 6 for Figure 1 Another schematic diagram of the position of the light source of the skin care device shown. In some embodiments, along the second direction H2, the reflective cavity is symmetrical about the first axis L1, the first axis L1 is parallel to the first direction H1, and all the light sources 22 are arranged symmetrically about the first axis L1. Then, 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 multiple light sources 22 through the inner wall of the reflective cavity can be more uniform.

[0086] In some embodiments, the reflective member 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, and the connecting portion 212 faces the light outlet 11, so that the first straight portion 211, the connecting portion 212, and the second straight portion 213 surround and form a reflective cavity with an opening facing the light outlet 11. Thus, part of the light emitted by the light source 22 may be emitted directly from between the first straight portion 211 and the second straight portion 213 toward the light outlet 11, and another part of the light emitted by the light source 22 may 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.

[0087] In some embodiments, the connecting portion 212 includes an arcuate surface. One end of the arcuate surface in the circumferential direction is connected to the first straight portion 211. The other end of the arcuate 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 a parabolic shape, 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.

[0088] Optional, please continue to refer to Figure 7 , Figure 7 for Figure 1The second structural schematic diagram of the reflective component of the skin care device shown in FIG. The connecting portion 212 may also include at least two focusing curved surfaces 2121, each of which is arranged corresponding to a light source 22, so that each focusing curved surface 2121 provides a good focusing effect for the corresponding light source 22, which is not limited in the embodiments of the present application.

[0089] In some embodiments, the connecting portion 212 is disposed around 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.

[0090] 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 each position of the light outlet 11.

[0091] It is understandable that the light source 22 may be completely located in the space enclosed by the connecting portion 212 , or the light source 22 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.

[0092] For example, please continue to refer to Figure 8 , Figure 8 for Figure 2 The light source of the skin care device is shown in the figure. The light source 22 is a lamp tube, and the length direction, the first direction H1, and the second direction H2 of the lamp tube are perpendicular to each other. At least one end of the lamp tube in the length direction is located outside the connecting portion 212. In 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 less than or equal to one fifth of the total length of the lamp tube.

[0093] 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 the embodiments of the present application.

[0094] 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 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 equipment.

[0095] Please continue to refer to Fig. 9 , Fig. 9 for Figure 8Schematic diagram of the structure after the light source is installed with the isolating member. 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 on the circuit board 300 and is located in the reflective cavity and is electrically connected to the circuit board 300. In addition, the light source 22 can be a lamp tube, each light source 22 is arranged close to 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 isolating member 23. The isolating member 23 is sleeved outside at least two light sources 22, and separates the reflective component 21 from 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.

[0096] Of course, the skin care device may also include a conductive bracket 500, which may be 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 is located in the reflective cavity and is electrically connected to the circuit board 300. In addition, the light source 22 may be a lamp tube, each light source 22 is arranged close to 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, at this time, the skin care device may also include an isolator 23. The isolator 23 is sleeved outside the conductive bracket 500, and the isolator 23 separates the reflective component 21 from 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.

[0097] Specifically, 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, an isolation member 23 is provided outside the conductive bracket 500.

[0098] Next, the conductive bracket 500 may be located outside the reflective cavity or may be disposed through the reflective component 21 for further explanation.

[0099] 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 disposed 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.

[0100] 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 penetrated in 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 from the conductive bracket 500.

[0101] 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.

[0102] In this way, the isolating member 23 is used to separate the reflective component 21 and the conductive bracket 500 to isolate the reflective component 21 and the conductive bracket 500 to avoid leakage of electricity from the reflective component 21 to the conductive bracket 500 or from the conductive bracket 500 to the reflective component 21, so as to provide safety in use.

[0103] The isolating member 23 being sleeved outside the at least two light sources 22 has at least the following two meanings.

[0104] The ends of the same side of the multiple lamp tubes may be inserted into the same isolating member 23, for example, different lamp tubes in the multiple lamp tubes matched with the same isolating member 23 may be inserted into different isolating holes of the isolating member 23 to achieve isolation. Alternatively, different lamp tubes may be separated by different isolating members 23, which is not limited in the present embodiment.

[0105] The isolating member 23 being sleeved outside the conductive support 500 has at least the following two meanings.

[0106] Adjacent conductive brackets 500 may all be inserted into the same isolating member 23, such as, among the multiple conductive brackets 500 matched with the same isolating member 23, different conductive brackets 500 are inserted into different isolation holes of the isolating member 23 to achieve isolation. Alternatively, different conductive brackets 500 may also be separated by different isolating members 23, which is not limited in the embodiment of the present application.

[0107] It is also understandable that the isolating member 23 may be made of an insulating material, such as rubber, or other insulating materials such as ceramics, which is not limited in the present embodiment.

[0108] For example, the skin care device also includes a conductive bracket 500, which is installed on the circuit board 300, and one end of at least one light source 22 is located outside the reflective cavity and electrically connected to the conductive bracket 500, so that the conductive bracket 500 is electrically connected to the circuit board 300.

[0109] Specifically, each end of each light source 22 in the length direction may be located outside a 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 a reflective cavity such as the connecting portion 212, which is not limited in the embodiments of the present application.

[0110] Optional, please continue to refer to Fig.10 , Fig.10 for Figure 1 The third structural schematic diagram of the conductive bracket of the skin care device is shown. The skin care device can also include a conductive bracket 500, which is mounted on the circuit board 300 and connected to the light source 22, so that the conductive bracket 500 is electrically connected to the circuit board 300; wherein at least one conductive bracket 500 is inserted through the reflective component 21, such as through the connecting portion 212.

[0111] Specifically, 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 penetrates the reflective component 21 .

[0112] In some embodiments, the light source 22 may abut against 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 makes the light source assembly 200 more compact as a whole, thereby facilitating the miniaturization of the skin care device.

[0113] Specifically, the light source 22 can be a lamp tube in combination with the above. When the size of the space in the connecting part 212 is certain, the light source 22 directly abuts against the connecting part 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 reflecting part 21 without increasing or slightly increasing the reflecting part 21, which is conducive to achieving a miniaturized design.

[0114] 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 may be respectively disposed at two trisection points of the connecting portion 212 .

[0115] When the number of the light sources 22 is greater than three, the plurality of light sources 22 may be disposed along the inner wall surface of the reflection cavity.

[0116] 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.

[0117] Continuing with the light source 22 being a lamp tube, the reflective component 21 can be electrically connected to the circuit board 300, so that the circuit board 300 can excite (i.e., trigger) the lamp tube through the reflective component 21. Furthermore, it can also be understood that the reflective component 21 is reused to excite the lamp tube, so that there is no need to wrap a wire (such as a filament) on the surface of the lamp tube to excite the lamp tube, thereby making the structure of the skin care device simpler, thereby reducing the production difficulty and manufacturing cost of the skin care device.

[0118] 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 winding a filament around the light source 22 , and this embodiment of the present application does not limit this.

[0119] If the light source 22 is a lamp tube, the lengths of all the lamp tubes can be the same, so that the brightness of the light emitted by different light sources 22 is more consistent, so that the brightness of each position at the light port 11 is more uniform.

[0120] 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 further explained and illustrated in combination with some optional structures of the conductive bracket 500.

[0121] Please continue to refer to Fig.11 , Fig.11 for Figure 2 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 arranged in sequence along the second direction H2.

[0122] At this time, the skin care device may further include a first conductive bracket 51 and a second conductive bracket 52, which are the above-mentioned conductive bracket 500. 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 bent and connected. 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, and the first direction H1, the second direction H2 and the third direction H3 are perpendicular to each other, and the second portion 522 is spaced apart from the first conductive bracket 51 along the second direction H2, and the second portion 522 is connected to the second light source 222.

[0123] In this way, at least two light sources 22 can be set with equal length, can be individually installed on the same circuit board 300, and supported in the reflective cavity, so as to achieve 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.

[0124] For example, the circuit board 300, the first light source 221, and the second light source 222 are arranged in sequence from top to bottom along the thickness direction of the skin care device, and the first conductive bracket 51 can be extended from top to bottom. The first portion 521 of the second conductive bracket 52 can also be extended from top to bottom, and the first portion 521 and the first conductive bracket 51 are spaced apart in the front-to-back or left-to-right direction.

[0125] For example, please refer to Figures 11 to 14 , Fig.12 for Fig.11 The schematic diagram of the structure of the conductive bracket shown in FIG. Fig.13 for Figure 1 A fourth structural schematic diagram of the conductive support of the skin care device shown, Fig.14 for Figure 1 The fifth structural schematic diagram of the conductive support of the skin care device shown in FIG. The first portion 521 may be located on a side of the first conductive support 51 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, which is not limited in the embodiment of the present application.

[0126] 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. Thus, the resistance of each conductive support 500 and / or each conductive support 500 is substantially the same, so that the current transmission between the circuit board 300 and each light source 22 is more consistent, so that the brightness of each position at the light output port 11 is more uniform.

[0127] Specifically, only the width of the first conductive support 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 support 51, the first part 521, and the second part 522 may all be equal, which is not limited in the embodiments of the present application.

[0128] In some embodiments, the light source 22 may be a lamp tube 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 all the lamp tubes have the same length in the third direction H3, so that the brightness of the light emitted by different light sources 22 is more consistent, so that the brightness of each position at the light port 11 is more uniform.

[0129] 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.

[0130] 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; among which, 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.

[0131] Of course, please continue to refer to Fig.15 , Fig.15 for Figure 1 The sixth structural schematic diagram of the conductive support of the skin care device is shown. In some other embodiments, the length of the light source 22 may also be different.

[0132] For example, the at least two light sources 22 are combined to include a first light source 221 and a second light source 222, and the circuit board 300, the first light source 221 and the second light source 222 are arranged in sequence 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 along the third direction H3 protrudes from the first light source 221. At this time, the skin care device can also 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 on the outside of the adjacent first conductive bracket 51.

[0133] The above are some examples of when the conductive brackets 500 are connected to the circuit board 300 on the same side of the light source assembly 200. The following will continue to explain the technical solution of the embodiment of the present application by taking the conductive brackets 500 connected to the circuit boards 300 on different sides of the light source assembly 200 as an example.

[0134] 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 away from the second light source 222. The second sub-circuit board 32 is located on a side of the second light source 222 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.

[0135] 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, so as to achieve 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.

[0136] The above are some examples of the light source assembly 200 in the embodiment of the present application. The following is a further example description in combination with some other optional structures in the embodiment of the present application.

[0137] Please continue to refer to Figures 16 to 18 , Fig.16 for Figure 1 A top view of the skin care device shown, Fig.17 for Fig.16A cross-sectional view of the skin care device along the AA direction, Fig.18 for Fig.17 The X in the figure provides an enlarged view. The skin care device further comprises a cold compress assembly 600 mounted on the housing 100 for applying cold compress to the skin.

[0138] For example, the cold compress assembly 600 may include a light guide component 61 and a cooling sheet 62. The light guide component 61 is disposed at the light outlet 11 to transmit the light emitted by the light source 22. The cooling sheet 62 is thermally connected to the light guide component 61; for example, the cooling sheet 62 is directly attached to the light guide component 61 or attached to the light guide component 61 through a thermal conductive medium such as thermal conductive silicone grease.

[0139] 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 as to come into contact with the skin. The light guide component 61 can not only transmit the light from 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.

[0140] 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 sheet 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.

[0141] Specifically, 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 couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the couple, thereby achieving the purpose of cooling.

[0142] 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.

[0143] 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 to filter the light emitted from the light source assembly 200 to the light guide member 61 .

[0144] For example, the filter 700 may be used to transmit light with a wavelength between 420 nanometers and 1200 nanometers, thereby forming IPL (intense pulsed light) light to irradiate the user's skin. In actual use, the wavelength of light required for hair removal may be between 420 nanometers and 1200 nanometers, and the wavelength of light required for skin rejuvenation may be between 600 nanometers and 1200 nanometers. In this way, the skin care device can have the three functions of cold compress, skin rejuvenation, and hair removal at the same time.

[0145] 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.

[0146] The housing 100 may be provided with a heat dissipation channel 12. The heat dissipation assembly 400 includes a fan 41, which is used to drive the air in the heat dissipation channel 12 to flow in a preset direction to dissipate heat for the light source assembly 200 and / or the cold compress assembly 600.

[0147] That is to say, the fan 41 can be used only for cooling the light source assembly 200, or only for cooling the cold compress assembly 600, or can be used for cooling both the light source assembly 200 and the cold compress assembly 600, which is not limited in the embodiments of the present application.

[0148] For example, when the heat dissipation component 400 can be used to dissipate heat for the cold compress component 600, the heat dissipation component 400 may also include a heat conductive member 42 and a heat sink 43. The heat conductive member 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 conductive 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 conductive medium such as thermal grease. The heat sink 43 is located on the side of the reflective component 21 away from the light outlet 11 and is at least partially located in the heat dissipation channel 12.

[0149] Therefore, after the heat conducting member 42 transfers the heat of the cooling fin 62 to the heat sink 43 , the fan 41 drives the air in the heat dissipation channel 12 to flow, thereby quickly completing the air cooling of the heat sink 43 .

[0150] For example, when the heat dissipation assembly 400 can be used to dissipate heat for both the light source assembly 200 and the cold compress assembly 600 , the heat dissipation channel 12 may include a first heat dissipation channel and a second heat dissipation channel.

[0151] The first heat dissipation channel is connected to the air outlet of the housing 100, such as between the first air outlet 13 and the fan 41, and 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.

[0152] 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.

[0153] In some embodiments, the second heat dissipation channel and the first heat dissipation channel may 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.

[0154] 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.

[0155] For example, please continue to combine Fig.19 , Fig.19 for Fig.16 The skin care device is shown in a cross-sectional view along the BB direction. The skin care device may further include a mounting bracket 800. The mounting bracket 800 is disposed in the housing 100 and is provided with a first mounting cavity 81, a connecting channel 82 and a second mounting cavity 83.

[0156] Among them, 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.

[0157] The heat sink 43 is at least partially disposed in the second installation cavity 83 , and the second installation cavity 83 is communicated with the air outlet of the fan 41 to form at least a portion of the second heat dissipation channel.

[0158] The mounting bracket 800 may 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.

[0159] The mounting bracket 800 may be provided with corresponding slots and ribs inside to facilitate the snap-in connection of the reflective component 21, the filter 700, etc., which is not limited in this embodiment of the present application.

[0160] The mounting bracket 800 may also be provided with corresponding openings so that the light guide component 61 and the cooling plate 62 etc. can be passed through the mounting bracket 800 , and this embodiment of the present application does not limit this.

[0161] The fan 41 may be a centrifugal fan, an axial flow fan, a cross flow fan, etc., which is not limited in the embodiment of the present application.

[0162] 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.

[0163] In some embodiments, the heat sink 43 may include a plurality of fins. The fins are protrudingly disposed on one side of the second end along the second direction H2 and are located in the heat dissipation channel 12. The fan 41 is located on the side of the fins away from the reflective component 21 along the first direction H1, and 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.

[0164] 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, so as 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.

[0165] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
