[0062] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present utility model. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model. In the present utility model, unless otherwise stated, the orientation words such as "upper" and "lower" usually refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; and "inner" and "outer" refer to the outline of the device.

[0063] In addition, "a plurality of" in the embodiments of the present utility model means two or more. In view of this, "a plurality of" in the embodiments of the present utility model can also be understood as "at least two". "At least one" can be understood as one or more, for example, understood as one, two or more. For example, including at least one means including one, two or more, and does not limit which ones are included. For example, including at least one of A, B, and C, then what can be included is A, B, C, A and B, A and C, B and C, or A and B and C.

[0064] It should be noted that in the embodiments of the present utility model, " / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone.

[0065] The embodiments of the present utility model provide a skin care device. The skin care device can be a hair removal device or a skin rejuvenation device, etc. Of course, the skin care device can also be any other device used to process the skin. The embodiments of the present utility model do not limit this.

[0066] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the skin care device according to the embodiments of the present utility model, Figure 2 is Figure 1 a cross-sectional view of the skin care device shown along the A-A direction. The skin care device includes a housing 100 and a light emitting assembly 200. The light emitting assembly 200 is disposed in the housing 100 and is used to generate light rays directed at the skin to be treated.

[0067] The skin care device further includes a heat dissipation component 300. The heat dissipation component 300 is disposed within the housing 100 for dissipating heat from the light emitting component 200.

[0068] Of course, the skin care device may further include a cold compress component 400. The cold compress component 400 is disposed within the housing 100 and is used for cold compressing the skin to be treated, so as to reduce or even eliminate the pain or heat sensation generated during hair removal or skin rejuvenation. Correspondingly, the heat dissipation component 300 may only be used for dissipating heat from the light emitting component 200, or may also be used for dissipating heat from both the light emitting component 200 and the cold compress component 400, thereby improving the cold compress effect of the cold compress component 400.

[0069] The above is an overall description of the skin care device in the embodiments of the present invention. The following will first give an example in conjunction with the light emitting structure of the skin care device.

[0070] The housing 100 is provided with a light emitting area 121. The light emitting component 200 faces the light emitting area 121 for generating light that is emitted from the light emitting area 121 towards the skin to be treated. The cold compress component 400 may be disposed at the light emitting area 121 for cold compressing the skin to be treated.

[0071] It should be noted that the light emitting area 121 may be an opening structure such as a light emitting port or a light emitting hole provided on the housing 100. Optionally, the light emitting area 121 may also be formed by some light transmissive areas on the housing 100, and the embodiments of the present invention do not make any limitations thereto.

[0072] It can be understood that, according to the different types of light generated by the light emitting component 200, the skin care device can be divided into different types. For example, the light emitting component 200 can be used to generate laser light, and it is a laser light source 21 component, and the skin care device is a laser type skin care device; for another example, the light emitting component 200 can be used to generate IPL light (intense pulsed light), and it is an IPL light source component (such as a xenon lamp component), and the skin care device is an intense pulsed light type skin care device; for another example, the light emitting component 200 can be an LED light source component.

[0073] In the present invention, the following mainly takes the light emitting component 200 as an IPL light source component as an example for description. The light emitting principle of this type of skin care device is as follows: The capacitor is connected to the power supply, and the voltage is boosted by the voltage conversion component to charge the capacitor. When the capacitor charge reaches the preset value and the controller receives the trigger signal, the electrical energy in the capacitor is released, and the instantaneous voltage can reach several hundred volts, thereby exciting the lamp tube to instantaneously emit intense pulsed light, and thus completing one light emission.

[0074] Please continue to refer to Figure 3 , Figure 3 For Figure 2Schematic structural diagram of the light-emitting component shown. In some embodiments, the light-emitting component 200 includes at least two light sources 21. The light source 21 can be a lamp tube or other types of light sources 21, and the embodiments of the present utility model do not limit this.

[0075] Furthermore, the nursing effect of the skin care device can be improved by the way of multiple light sources 21 emitting light. For example, multiple light sources 21 can be synchronously switched, so that the light source 21 component can perform skin care with a higher maximum power, thereby improving the nursing effect of the skin care device; or, different light sources 21 can emit light separately or in combination, so that the light source 21 component can have at least three light-emitting modes, so as to be adjusted to a more suitable light-emitting mode according to the actual needs of the user, and further improve the nursing effect of the skin care device.

[0076] It can also be understood that the number of light sources 21 or lamp tubes can be two, or three, four, five, and the embodiments of the present utility model do not limit this.

[0077] In some embodiments, the light-emitting component 200 further includes a reflecting cup 22, and at least part of the light source 21 is disposed in the reflecting cup 22, so that the reflecting cup 22 reflects part of the light emitted by the light source 21 to the light-emitting area 121, thereby increasing the light output of the light-emitting component 200, and further increasing the power of the skin care device.

[0078] Exemplarily, the reflecting cup 22 is provided with an arc-shaped groove 221, the notch of the arc-shaped groove 221 faces the light-emitting area 121, and at least part of the light source 21 is disposed in the arc-shaped groove 221. Then, continuing to take the light source 21 as a lamp tube as an example, it can be that the middle part of the lamp tube in the length direction is disposed in the arc-shaped groove 221, and the end parts of the lamp tube in the length direction are disposed outside the arc-shaped groove 221 for electrical connection. Thus, part of the light emitted by the middle of the lamp tube directly shoots towards the light-emitting area 121 from the notch of the arc-shaped groove 221, and the other part of the light shoots towards the inner wall of the arc-shaped groove 221 and is reflected to shoot towards the light-emitting area 121 from the notch of the arc-shaped groove 221, and further the light output of the light-emitting component 200 can be increased.

[0079] In some embodiments, the number of the arc-shaped grooves 221 can be at least two, and at least one light source 21 is disposed in each arc-shaped groove 221.

[0080] Optionally, it can also be that all the light sources 21 are disposed in the same arc-shaped groove 221, so that the light output of the light-emitting component 200 is more uniform. Then, continuing to take the skin care device as a hair removal device or a skin rejuvenation device as an example, the situation that some areas of the skin are not completely hair removed or rejuvenated due to weak brightness can be avoided, so as to improve the hair removal or skin rejuvenation effect.

[0081] Next, continue to take the light source 21 as a lamp tube and all the light sources 21 are arranged in the same arc-shaped groove 221 to illustrate the technical solution of the embodiment of the present invention by way of example.

[0082] A plurality of lamp tubes are evenly spaced along the inner circumferential side of the arc-shaped groove 221. Therefore, through the uniform distribution of the plurality of lamp tubes, the brightness at each position of the light-emitting area 121 can be made more consistent.

[0083] In some embodiments, the orthographic projections of the plurality of lamp tubes on the plane where the light-emitting area 121 is located are at least partially misaligned with each other, so that at least part of the light generated by each lamp tube can be at least partially directly projected onto the light-emitting area 121, thereby reducing the loss generated during the reflection of the light generated by the lamp tubes, and finally increasing the light output of the light-emitting component 200.

[0084] In some embodiments, three lamp tubes are distributed in a triangular shape. Among them, the distances from the two lamp tubes close to the light-emitting area 121 to the light-emitting area 121 are the same.

[0085] It can be understood that the light intensity of the light emitted by the lamp tube will decrease as the radiation distance increases. In the embodiment of the present invention, the distances from the two lamp tubes close to the light-emitting area 121 to the light-emitting area 121 are the same, so that the light brightness at each position of the light-emitting area 121 is more uniform.

[0086] The above is an example illustration of some structures of the light-emitting component 200 in the embodiment of the present invention. Next, continue to illustrate by way of example in combination with the electrical connection manner of the light-emitting component 200.

[0087] Please continue to refer to Figure 4 , Figure 4 which is a schematic structural diagram of the first conductive bracket provided by the embodiment of the present invention. In some embodiments, the skin care device may further include a circuit board assembly 500. The circuit board assembly 500 is disposed in the housing 100. The circuit board assembly 500 includes a circuit board 51 and a conductive bracket 52 mounted on the circuit board 51. The conductive bracket 52 is fixedly connected to the light-emitting component 200 to form an electrical connection.

[0088] In some embodiments, the distance between each lamp tube and the reflective cup 22 is less than a preset distance, so that the lamp tube can be excited by the reflective cup 22 to emit light.

[0089] For example, the lamp tube may be a xenon lamp tube, and both ends or poles of the xenon lamp tube are electrically connected to the circuit board 51 through the conductive bracket 52. At this time, the circuit board 51 can be electrically connected to the reflective cup 22, and the lamp tube is excited or triggered through the reflective cup 22, thereby reducing the components of the skin care device through the reuse of the reflective cup 22, making the skin care device more compact.

[0090] In some embodiments, the preset distance may be less than or equal to 2 millimeters. For example, the distance between the reflector cup 22 and the lamp tube is 2 millimeters, 1.4 millimeters, 0.5 millimeters, or 0 millimeters. Of course, when the distance between the reflector cup 22 and the lamp tube is 0 millimeters, it can also be understood that the reflector cup 22 and the lamp tube are in direct contact.

[0091] Optionally, wires (such as filaments) may be wound around the surface of the lamp tube, and the wires are electrically connected to the circuit board 51 for exciting the lamp tube. The embodiments of the present invention do not limit this.

[0092] In some embodiments, the heat dissipation component 300 may include a blower 31. The blower 31 is disposed inside the housing 100 and is used to drive air to flow along the length direction of the light-emitting component 200 through the light-emitting component 200, thereby dissipating heat from the light-emitting component 200.

[0093] Based on this, in the first structure of the conductive bracket 52 provided by the embodiments of the present invention, the conductive bracket 52 is fixedly connected to the end in the length direction of the light-emitting component 200 to form an electrical connection. The thickness direction of the conductive bracket 52 intersects (for example, is perpendicular to) the length direction of the light-emitting component 200, and at least one side edge in the width direction of the conductive bracket 52 is recessed inward for air to flow along the length direction of the light-emitting component 200.

[0094] Therefore, it can also be simply understood that the middle part of the conductive bracket 52 is narrower, so that the air resistance when the air driven by the blower 31 passes through the conductive bracket 52 is smaller, thereby increasing the flow rate of the air and finally improving the heat dissipation effect.

[0095] In some embodiments, the light-emitting component 200 includes at least two lamp tubes (or light sources 21), and the ends of different lamp tubes are connected to different conductive brackets 52. Thus, different lamp tubes can emit light separately or in combination.

[0096] Here, it can be understood that the length direction of the light-emitting component 200 may be the length direction of the lamp tube.

[0097] Exemplarily, please continue to refer to Figure 5 , Figure 5 For Figure 4Assembly schematic diagram of the light-emitting component and the first heat dissipation component shown. The conductive bracket 52 may include a first conductive bracket 521 and two second conductive brackets 522. The first conductive bracket 521 extends along the direction of the circuit board 51 towards the lamp tube. Both side edges in the width direction of the first conductive bracket 521 are recessed inward to allow air to flow along the length direction of the light-emitting component 200. The two second conductive brackets 522 are respectively located on different sides of the first conductive bracket 521 in the width direction. One side edge of the second conductive bracket 522 close to the first conductive bracket 521 is recessed away from the first conductive bracket 521.

[0098] Thus, independent switch control of three lamp tubes can be achieved through the first conductive bracket 521 and the two second conductive brackets 522, so that the light-emitting component 200 has a richer working mode. On this basis, both sides of the first conductive bracket 521 in the width direction are recessed to make the air resistance at the first conductive bracket 521 lower, and the recess at the second conductive bracket 522 makes the air resistance at the second conductive bracket 522 lower, so that the overall air resistance at the light-emitting component 200 can be effectively reduced, and finally the light-emitting component 200 can be better cooled.

[0099] In some embodiments, the second conductive bracket 522 includes a first section 5221 and a second section 5222. The first section 5221 is electrically connected to the circuit board 51. One side edge of the first section 5221 close to the first conductive bracket 521 is recessed away from the first conductive bracket 521. The second section 5222 is located on the side of the first conductive bracket 521 close to the light-emitting area 121 and is connected to one side of the first section 5221 close to the first conductive bracket 521. The second section 5222 is also connected to the end of the lamp tube in the length direction.

[0100] Therefore, it can also be understood that the second conductive bracket 522 has an L-shaped structure. Furthermore, in the case where the distances between multiple lamp tubes are relatively close, the distance between the first section 5221 and the first conductive bracket 521 can be prevented from being too close, thereby improving the isolation effect between the first conductive bracket 521 and the second conductive bracket 522.

[0101] In some embodiments, along the length direction of the light-emitting component 200 (or the lamp tube), the orthographic projection of the first section 5221 may be located on the outer peripheral side of the orthographic projection of the reflector 22, so as to reduce and avoid the first section 5221 blocking the air from directly flowing into the reflector 22 from the end of the reflector 22, and further improving the heat dissipation effect of the light-emitting component 200.

[0102] Please refer to Figure 5 and Figure 6 , Figure 6 For Figure 5Schematic diagram of the fixing structure of the first heat dissipation component shown. In some embodiments, the heat dissipation assembly 300 further includes a first heat dissipation component 32. The first heat dissipation component 32 is thermally connected to the light-emitting component 200 to dissipate heat from the light-emitting component 200. Inside the housing 100, there is a first rib 3411 for clamping the first heat dissipation component 32. Among them, along the length direction of the lamp tube, the orthographic projection of the first section 5221 at least partially coincides with the orthographic projection of the first rib 3411, so that the overall orthographic projection area of the first rib 3411 and the first section 5221 in the length direction of the lamp tube is smaller, so as to reduce the wind resistance when the air flow driven by the fan 31 passes through the light-emitting component 200, thereby improving the heat dissipation effect of the light-emitting component 200.

[0103] It can also be understood that the number of the first ribs 3411 can be at least one group, and each group of first ribs 3411 is arranged at intervals along the length direction of the light-emitting component 200, and the first heat dissipation component 32 is clamped between two first ribs 3411 of the same group.

[0104] In some embodiments, the first conductive bracket 521 has a first card slot 5211 for fixing the lamp tube. The second section 5222 has a second card slot 5223 for fixing the lamp tube. The openings of the first card slot 5211 and the second card slot 5223 both face the light-emitting area 121, so as to facilitate connecting a plurality of lamp tubes to the first conductive bracket 521 and the second conductive bracket 522 respectively from the same direction, so that the skin care device of the embodiment of the present utility model has the advantage of being convenient for assembly.

[0105] The above is an example description of the first structure of the conductive bracket 52 in the embodiment of the present utility model.

[0106] Please continue to refer to Figure 7 , Figure 7 which is a schematic diagram of the structure of the second conductive bracket provided by the embodiment of the present utility model. Optionally, in the second structure of the conductive bracket 52 provided by the embodiment of the present utility model, the conductive bracket 52 includes a third conductive bracket 53, and the third conductive bracket 53 includes a third section 531 and a fourth section 532 that are bent and connected. The length or width direction of the third section 531 extends along the length direction of the light-emitting component 200 and is connected to the circuit board 51 for air to flow through the light-emitting component 200 from both sides in the thickness direction of the third section 531. The length direction of the light-emitting component 200 extends along the thickness direction of the fourth section 532 and is fixedly connected to the fourth section 532 to form an electrical connection.

[0107] Then, since the thickness directions of both the third section 531 and the fourth section 532 are the same as the length direction of the light-emitting component 200, the embodiment of the present utility model can effectively reduce the wind resistance when the air flow driven by the fan 31 passes through the third section 531, thereby improving the cooling effect on the light-emitting component 200. On this basis, taking the third conductive bracket 53 formed by a bending process as an example, the part of the third conductive bracket 53 located between the circuit board 51 and the light-emitting component 200 can be formed into the third section 531 and the fourth section 532 only by one bending, so that the third conductive bracket 53 has the advantage of being easy to form, and thus the third conductive bracket 53 has the advantages of low wind resistance and being easy to form.

[0108] The above are some illustrative examples of the circuit board assembly 500 in the embodiment of the present utility model. Next, the technical solution of the embodiment of the present utility model will be further illustrated in combination with the air duct structure in the skin care device.

[0109] Please continue to refer to Figure 8 , Figure 8 For Figure 2 the schematic diagram of the air duct structure of the skin care device shown. In some embodiments, a first air duct 3412 and a second air duct 3413 are further provided in the housing 100. Both the first air duct 3412 and the second air duct 3413 are communicated with the fan 31, so that the fan 31 can drive the air flow through the first air duct 3412 and the second air duct 3413. The first air duct 3412 is used for dissipating heat from the light-emitting component 200, and the second air duct 3413 is used for dissipating heat from the cold compress component 400.

[0110] Exemplarily, both the first air duct 3412 and the second air duct 3413 extend along the length direction of the light-emitting component 200, and at least a part of the light-emitting component 200 is disposed in the first air duct 3412, so that the fan 31 can drive the air to flow through the first air duct 3412 along the length direction of the light-emitting component 200 to dissipate heat from the light-emitting component 200.

[0111] As mentioned above, in some embodiments, the heat dissipation component 300 further includes a first heat dissipation part 32. The first heat dissipation part 32 is thermally connected to the light-emitting component 200 to dissipate heat from the light-emitting component 200. A first rib 3411 for clamping the first heat dissipation part 32 is provided inside the housing 100. Among them, the first heat dissipation part 32 can be disposed in the first air duct 3412, and the first rib 3411 can be formed on the inner wall of the first air duct 3412.

[0112] For example, the first heat dissipation component 32 may include a first heat conductive member 321 and a plurality of first heat sinks 322. The first heat conductive member 321 is an arc-shaped structure surrounding the outer peripheral side of the reflective cup 22. The first heat conductive member 321 is heat-conductively connected to the reflective cup 22, for example, the first heat conductive member 321 is directly attached to the reflective cup 22, or is indirectly attached to the reflective cup 22 through a heat conductive medium such as thermal grease, so that the heat at the reflective cup 22 can be quickly transferred to the first heat conductive member 321. The first heat sink 322 is arranged on the side of the first heat conductive member 321 away from the reflective cup 22, so that the contact area between the first heat dissipation component 32 and the air in the first air duct 3412 can be increased through the plurality of first heat sinks 322, thereby improving the heat dissipation effect.

[0113] In some embodiments, the heat dissipation assembly 300 also includes a second heat dissipation component 35, which is thermally connected to the cold compress assembly 400 and is at least partially located in the second air duct 3413, so that the fan 31 can drive air to flow through the second air duct 3413 to dissipate heat for the cold compress assembly 400.

[0114] Exemplarily, the second heat dissipation component 35 includes a second heat conductive member 351 and a plurality of second heat sinks 352 mounted on the second heat conductive member 351. The second heat conductive member 351 is thermally connected to the cold compress assembly 400, for example, the second heat conductive member 351 is directly attached to the cold compress assembly 400, or is indirectly attached to the cold compress assembly 400 through a heat conductive medium such as thermal conductive silicone grease, so that the heat at the reflective cup 22 can be quickly transferred to the second heat conductive member 351. The second heat sink 352 is at least partially located in the second air duct 3413, so that the contact area between the second heat dissipation component 35 and the air can be increased through the second heat sink 352, thereby improving the heat dissipation effect.

[0115] Next, the second heat dissipation component 35 is further described by way of example in combination with the structure of the cold compress assembly 400 .

[0116] It should be noted that the light exit area 121 may be an opening structure such as a light exit port or a light exit hole provided on the housing 100. Optionally, the light exit area 121 may also be formed by some light-transmitting areas on the housing 100, which is not limited in the embodiment of the utility model.

[0117] The cold compress component 400 is disposed at the light-emitting area 121. The cold compress component 400 can be installed inside the light-emitting area 121, or can be disposed on the periphery of the light-emitting area 121, or part of the cold compress component 400 is disposed inside the light-emitting area 121 and part is disposed on the periphery of the light-emitting area 121. The embodiments of the present utility model do not limit this. It should be noted that when the cold compress component 400 is installed inside the light-emitting area 121, the cold compress component 400 directly performs cold compress on the skin to be treated; when the cold compress component 400 is disposed on the periphery of the light-emitting area 121, the cold compress component 400 first performs cold compress on the skin on the periphery of the skin to be treated, so as to transfer the cold energy to the skin to be treated through the skin on the periphery, so as to indirectly perform cold compress on the skin to be treated.

[0118] For example, the cold compress component 400 may include a light guide member 41 and a thermoelectric cooler 42. The light-emitting area 121 is an opening structure such as a light-emitting port or a light-emitting hole. The light guide member 41 is disposed in the light-emitting area 121 to transmit the light emitted by the light-emitting component 200. The thermoelectric cooler 42 is thermally connected to the light guide member 41. For example, the thermoelectric cooler 42 is directly attached to the light guide member 41 or is attached to the light guide member 41 through a thermal conductive medium such as thermal conductive silicone grease.

[0119] Furthermore, the thermoelectric cooler 42 can be used to cool the light guide member 41. The cooled light guide member 41 is exposed from the light-emitting area 121, so that it can be in contact with the skin. The light guide member 41 can not only transmit the light of the light source 21 to care for the user's skin, but also provide cold compress for the user by cooling with the thermoelectric cooler 42.

[0120] Specifically, the thermoelectric cooler 42 is also called a semiconductor refrigeration sheet. Utilizing the Peltier effect of semiconductor materials, when direct current passes through an electric couple formed by two different semiconductor materials connected in series, heat can be absorbed and released at both ends of the electric couple respectively, and the purpose of refrigeration can be achieved.

[0121] The light guide member 41 can be made of sapphire or other light guide materials. The embodiments of the present utility model do not limit this.

[0122] In an alternative embodiment, the cold compress component 400 may further include a cold compress member (not shown in the figure) and a thermoelectric cooler 42. The light-emitting area 121 is an opening structure such as a light-emitting port or a light-emitting hole. The cold compress member is disposed on the opening end surface of the light-emitting area 121. The thermoelectric cooler 42 is thermally connected to the cold compress member; for example, the thermoelectric cooler 42 is directly attached to the cold compress member or is attached to the cold compress member through a thermal conductive medium such as thermal conductive silicone grease.

[0123] Furthermore, the thermoelectric cooler 42 can be used to cool the cold compress member. The cooled cold compress member is exposed from the light-emitting area 121 so that it can be in contact with the skin to provide cold compress for the user.

[0124] For example, the cold compress member may be an annular metal member disposed around the light-emitting area 121 or the like.

[0125] In another alternative embodiment, the cold compress assembly 400 includes a cold compress member having a flow cavity (not shown in the figure), a refrigeration medium (such as a refrigerating liquid or a refrigerating gas) that is flowably disposed in the flow cavity, and a driving device (such as a compressor or the like) for driving the refrigeration medium to circulate and flow. In this way, the cold compress function of the cold compress member can be realized by using the cooling medium. The light-emitting area 121 is an opening structure such as a light-emitting port or a light-emitting hole, and the cold compress member is disposed in a surrounding shape on the opening end surface of the light-emitting area 121.

[0126] Correspondingly, the above-mentioned second heat dissipation component 35 (for example, the second of the second heat dissipation component 35) can be directly or indirectly attached to the corresponding refrigeration chip 42 to achieve thermal conduction connection.

[0127] Please continue to refer to Figure 9 , Figure 9 For Figure 1 the cross-sectional view of the skin care device shown Figure 2 . In some embodiments, the housing 100 is provided with a first air inlet 111. The first air inlet 111 is located on a side of the light-emitting assembly 200 in the length direction away from the blower 31. The first air inlet 111 is disposed opposite to and communicated with the ends of the first air duct 3412 and the second air duct 3413 that are away from the blower 31. Of course, it can also be understood that the first air inlet 111 is located on a side of the first air duct 3412 away from the blower 31, and the first air inlet 111 is respectively communicated with the ends of the first air duct 3412 and the second air duct 3413 that are away from the blower 31.

[0128] Furthermore, the blower 31 can drive the air outside the housing 100 to directly flow into the first air duct 3412 and the second air duct 3413 from the first air inlet 111. Then, compared with the air outside the housing 100 flowing into the first air duct 3412 and the second air duct 3413 after multiple reversals at the first air inlet 111, the embodiment of the present invention can effectively reduce the air resistance when the air outside the housing 100 flows into the first air duct 3412 and the second air duct 3413, thereby improving the heat dissipation effect at the first air duct 3412 and the second air duct 3413. Similarly, when the blower 31 drives the air in the first air duct 3412 and the second air duct 3413 to directly flow out of the housing 100 from the first air inlet 111, the embodiment of the present invention can effectively reduce the air resistance when the air in the first air duct 3412 and the second air duct 3413 flows out, thereby improving the heat dissipation effect at the first air duct 3412 and the second air duct 3413.

[0129] In some embodiments, the housing 100 is further provided with a second air outlet 112. The second air outlet 112 is located on the side of the blower 31 facing away from the light-emitting assembly 200. Of course, it can also be understood that the second air outlet 112 is located on the side of the blower 31 facing away from the first air duct 3412, and the second air outlet 112 is in communication with the air outlet of the blower 31.

[0130] Furthermore, the blower 31 can drive the air outside the housing 100 to directly flow into the first air duct 3412 and the second air duct 3413 from the second air outlet 112. Therefore, compared with the air outside the housing 100 flowing into the first air duct 3412 and the second air duct 3413 after multiple direction changes at the second air outlet 112, the embodiment of the present invention can effectively reduce the air resistance when the air outside the housing 100 flows into the first air duct 3412 and the second air duct 3413, thereby improving the heat dissipation effect at the first air duct 3412 and the second air duct 3413. Similarly, when the blower 31 drives the air in the first air duct 3412 and the second air duct 3413 to directly flow out of the housing 100 from the second air outlet 112, the embodiment of the present invention can effectively reduce the air resistance when the air in the first air duct 3412 and the second air duct 3413 flows out, thereby improving the heat dissipation effect at the first air duct 3412 and the second air duct 3413.

[0131] Exemplarily, the housing 100 can be in a long strip shape, so that the housing 100 has a length direction. At this time, the length directions of the light-emitting assembly 200, the first air duct 3412, and the second air duct 3413 are all the same as the length direction of the housing 100. The first air outlet 111 is located at one end of the housing 100 in the length direction, and the second air outlet 112 is located at the other end of the housing 100 in the length direction.

[0132] At this time, taking the first air outlet 111 as the air outlet of the housing 100 and the second air outlet 112 as the air inlet of the housing 100 as an example, under the drive of the blower 31, a part of the air flows into the housing 100 from the second air outlet 112, and then sequentially flows through the blower 31, the first air duct 3412, and the first air outlet 111 along the length direction of the housing 100 and then flows out of the housing 100 to realize an external circulation; another part of the air flows into the housing 100 from the second air outlet 112, and then sequentially flows through the blower 31, the second air duct 3413, and the first air outlet 111 along the length direction of the housing 100 and then flows out of the housing 100 to realize an external circulation.

[0133] Please continue to refer to Figure 10 , Figure 10 For Figure 1 the structural schematic diagram of the skin care device shown. Correspondingly, in order to prevent the user from blocking the air inlet and outlet of the housing 100 during use, or to prevent the hot air flowing out of the housing 100 from blowing towards the user, the light-emitting area 121 can be formed on the circumferential surface of one end of the housing 100 in the length direction.

[0134] For example, the shell 100 includes a main shell 11 and a head shell 12. The main shell 11 is in the shape of an elongated strip to constitute the main structure of the shell 100. A first air outlet 111 is provided on one end face of the main shell 11 in the length direction. A second air outlet 112 is provided on the other end of the main shell 11 in the length direction. Specifically, the second air outlet 112 may be provided on one end face of the main shell 11 in the length direction, or may be provided on the peripheral surface of the end of the main shell 11 away from the first air outlet 111, and the embodiment of the utility model does not limit this. The head shell 12 is provided on the peripheral surface of one end of the main shell 11 close to the first air outlet 111, and a light emitting area 121 is provided on one end face of the head shell 12 away from the main shell 11.

[0135] Correspondingly, the first air duct 3412 and / or the second air duct 3413 may both be located in the main shell 11, or may both be partially located in the main shell 11 and partially located in the head shell 12, and the embodiment of the utility model is not limited to this.

[0136] Please continue to refer to Figure 11 , Figure 11 for Figure 1 Cross-sectional view of the skin care device shown Figure 3 In some embodiments, the skin care device further includes a bracket assembly 34, the bracket assembly 34 is disposed in the housing 100, and the bracket assembly 34 or the bracket assembly 34 and the housing 100 form at least one of the first air duct 3412 and the second air duct 3413. Therefore, compared with directly forming the first air duct 3412 and the second air duct 3413 by the housing 100, forming at least part of the air duct by the bracket assembly 34 can reduce the difficulty of forming the corresponding air duct.

[0137] Please continue to refer to Figure 12 , Figure 12 for Figure 11 Schematic diagram of the structure of the bracket assembly shown. Exemplarily, the bracket assembly 34 includes a first bracket 341. The first bracket 341 is arranged in the housing 100. The first bracket 341 includes a bottom plate 3414 and two side plates 3415. The bottom plate 3414 is arranged on the side of the light emitting assembly 200 away from the light emitting area 121. The two side plates 3415 are connected to the side of the bottom plate 3414 close to the light emitting area 121 and are arranged at intervals. A first air duct 3412 is formed between the bottom plate 3414 and the two side plates 3415. A second air duct 3413 is formed between the side of each side plate 3415 away from the first air duct 3412 and the housing 100, and each second air duct 3413 cooperates with a second heat dissipation component 35.

[0138] Please continue to refer to Figure 13 , Figure 13 for Figure 12Exploded view. In some embodiments, the circuit board 51 includes a first circuit board 511 and a second circuit board 512. The second circuit board 512 is located on the side of the first circuit board 511 close to the light-emitting component 200 and is electrically connected to the light-emitting component 200. Therefore, compared with using a single longer main control circuit board to replace the first circuit board 511 and the second circuit board 512, the embodiment of the present utility model can reduce the total length of the circuit board assembly 500 in the length direction of the first circuit board 511, thereby facilitating reducing the total length of the skin care device in the length direction of the first circuit board 511.

[0139] In some embodiments, electrical components are further provided between the first circuit board 511 and the second circuit board 512, such as energy storage capacitors, IGBTs, switching tubes, relays, and the like.

[0140] When the number of electrical components is one, the electrical component can be installed on the first circuit board 511 or the second circuit board 512. When the number of electrical components is multiple, the electrical components can all be installed on the first circuit board 511 or the second circuit board 512, or part of the electrical components can be installed on the first circuit board 511 and part on the second circuit board 512, so as to make full use of the space between the first circuit board 511 and the second circuit board 512.

[0141] In some embodiments, the bracket assembly 34 further includes a second bracket 342, and the second bracket 342 is connected to the first circuit board 511. The second bracket 342 includes an abutting portion 3421 and a plurality of first clamping portions 3422 provided on the abutting portion 3421. The first clamping portions 3422 are clamped and fixed to the side plate 3415 of the first bracket 341. The second circuit board 512 is clamped between the abutting portion 3421 and the bottom plate 3414 of the first bracket 341. Thus, through the cooperation of the first bracket 341 and the second bracket 342, the installation stability of the second circuit board 512 can be improved, and at the same time, it has the advantage of convenient installation.

[0142] In some embodiments, the side plate 3415 may be provided with a second clamping portion 3416, and the second clamping portion 3416 is clamped and fixed to the first clamping portion 3422. For example, one of the first clamping portion 3422 and the second clamping portion 3416 is a clamping protrusion, and the other is provided with a clamping hole matching the clamping protrusion.

[0143] In some embodiments, at least two first clamping portions 3422 are provided on each side of the first bracket 341 along the width direction of the first circuit board 511, so that the clamping stability between the first bracket 341 and the second bracket 342 can be improved through multiple clamps.

[0144] In some embodiments, the first bracket 341 is provided with a plurality of third clamping portions 3417, and the third clamping portions 3417 are clamped to the second circuit board 512.

[0145] Exemplarily, the second circuit board 512 is provided with a plurality of clamping positions 5121, and at least one third clamping portion 3417 is clamped in each clamping position 5121. For example, the clamping position 5121 may have a clamping notch for engaging with the third clamping portion 3417. Thus, the stability and reliability of the overall connection of the first bracket 341, the second bracket 342, and the second circuit board 512 can be further improved through the third clamping portion 3417.

[0146] The above are some examples of the air duct structure inside the housing 100 in the embodiments of the present invention. Next, examples will continue to be given in combination with other structures of the skin care device.

[0147] As Figure 10 shown, the outer surface of the housing 100 includes a light-emitting surface 123, and the light-emitting area 121 is located on the light-emitting surface 123. Among them, the skin care device may further include a rotating member 600, and the rotating member 600 is rotatably installed on the housing 100. The rotating member 600 also at least partially protrudes from the light-emitting surface 123 so that the rotating member 600 can roll on the skin to be treated.

[0148] Then, taking the example that a user cares for multiple areas to be treated on the arm, the user can first press the rotating member 600 against the user's arm, and then drive the housing 100 or the skin care device to move between multiple areas to be treated through the rolling of the rotating member 600 on the skin, so that the light-emitting assembly 200 completes the care of multiple areas to be treated. During this process, by rolling the rotating member 600 on the skin, the friction between the skin care device and the skin can be reduced, thereby avoiding inconvenient movement of the skin care device or excessive friction on the skin resulting in skin abrasion, discomfort, etc. In addition, compared with the user lifting the skin care device from one area to be treated and then placing it on another area to be treated, the rotating member 600 makes the skin care device have the advantages of being easy to move and having a short moving path, thereby improving the skin care efficiency.

[0149] The rotating member 600 may include at least one of a ball, a roller, and a roller shaft, and the embodiments of the present invention do not limit this.

[0150] Please continue to refer to Figure 14 , Figure 14 For Figure 10 the structural schematic diagram of the rotating member and the housing shown. Exemplarily, the rotating member 600 may include a rotating member body 61 and a mounting shaft 62. The rotating member body 61 passes through the housing 100 to partially protrude from the light-emitting surface 123. The mounting shaft 62 is connected to the rotating member body 61, and the mounting shaft 62 is rotatably installed on the housing 100.

[0151] It should be noted that the mounting shaft 62 is rotatably mounted on the housing 100. It can be that the mounting shaft 62 is in direct contact with the housing 100 to form a rotational connection, or the mounting shaft 62 can be rotatably mounted on some components fixed to the housing 100 and thus indirectly rotatably mounted on the housing 100. The embodiments of the present invention do not limit this.

[0152] The rotating member body 61 can be columnar or spherical. When the rotating member body 61 is columnar, the mounting shaft 62 can be connected to the end of the rotating member body 61. The embodiments of the present invention do not limit this.

[0153] Taking the rotating member body 61 being columnar as an example, each end of the rotating member body 61 is provided with a mounting shaft 62. Optionally, the rotating member body 61 can also be a roller or a ball, and the number of mounting shafts 62 is two. The two mounting shafts 62 are coaxially arranged and located on the opposite sides of the rolling member body. Thus, the mounting of the rotating member body 61 can be made more stable and reliable through the two mounting shafts 62.

[0154] In some embodiments, the mounting shaft 62 can be multi-sided columnar, so that during the rotation of the mounting shaft 62, the mounting shaft 62 can radially jump periodically to provide vibration feedback when the rotating member 600 drives the skin care device to roll on the surface of the skin to be treated.

[0155] In some embodiments, the mounting shaft 62 is an eccentric shaft, so that during the rotation of the mounting shaft 62, the mounting shaft 62 can radially jump periodically to provide vibration feedback when the rotating member 600 drives the skin care device to roll on the surface of the skin to be treated.

[0156] Please continue to refer to Figure 15 , Figure 15 For Figure 14 another structural schematic diagram of the rotating member shown. In some embodiments, the mounting shaft 62 is provided with an elastic telescopic member 621, and the elastic telescopic member 621 is configured to be able to extend or retract following the rotation of the mounting shaft 62. For example, the elastic telescopic member 621 can be a ball plunger screw, etc., so that during the rotation of the mounting shaft 62, the mounting shaft 62 can radially jump periodically to provide vibration feedback when the rotating member 600 drives the skin care device to roll on the surface of the skin to be treated.

[0157] Please continue to refer to Figure 16 , Figure 16 For Figure 14Exploded view. In some embodiments, a light-emitting hole is provided on one surface of the housing 100 to form a light-emitting area 121. The housing 100 is provided with a mounting hole 122 therethrough, and the mounting hole 122 is at least partially located on the light-emitting surface 123. The mounting hole 122 is disposed adjacent to the light-emitting area 121. The rotating member body 61 is inserted through the mounting hole 122 to protrude partially from the light-emitting surface 123.

[0158] It can be understood that by disposing the mounting hole 122 adjacent to the light-emitting area 121, the distance between the rotating member body 61 and the light-emitting area 121 can be made closer, thereby avoiding the need to provide a larger area on the light-emitting surface 123 of the housing 100 to arrange the mounting hole 122 and the light-emitting area 121 with a large spacing. Furthermore, during use, the user can more conveniently and accurately fit the light-emitting area 121 to the skin to be treated.

[0159] In some embodiments, a mounting groove 124 is further provided on the inner wall of the housing 100. The mounting groove 124 communicates with the mounting hole 122. The mounting shaft 62 is rotatably disposed in the mounting groove 124. Thus, by hiding the connection between the rotating member 600 and the housing 100 inside the housing 100, it can be avoided that the rotating member body 61 is exposed at the connection with the housing 100 and accidentally damaged. Furthermore, the stability and reliability of the installation of the rotating member 600 can be improved.

[0160] Please continue to refer to Figure 17 , Figure 17 is Figure 10 Partial enlarged view at X. In some embodiments, the outer surface of the housing 100 further includes a side surface 125. The light-emitting surface 123 and the side surface 125 are connected and face different directions. The mounting hole 122 is partially located on the light-emitting surface 123 and partially located on the side surface 125, so that the rotating member body 61 protrudes partially from the light-emitting surface 123 and partially from the side surface 125.

[0161] It can be understood that since the skin itself has a certain elasticity, when the rotating member 600 and the light-emitting surface 123 are abutted against the skin to be treated, the skin to be treated will be squeezed to form a concave pit, and the light-emitting surface 123 and a part of the side surface 125 will be received in the concave pit. At this time, since the rotating member body 61 protrudes partially from the light-emitting surface 123, the friction between the light-emitting surface 123 and the skin to be treated can be reduced, and since the rotating member body 61 also protrudes partially from the side surface 125, the friction between the side surface 125 and the skin to be treated can be reduced. Thus, when the rotating member 600 rolls on the skin to be treated, it is smoother, thereby improving the user experience.

[0162] In some embodiments, the height by which the rotating member 600 (e.g., the rotating member body 61 of the rotating member 600) protrudes from the outer surface of the housing 100 is less than or equal to 1.2 millimeters, so as to avoid the rotating member body 61 protruding too much from the outer surface of the housing 100, which may cause the light-emitting surface 123 not to fit well with the skin to be treated. Thus, both the skin care effect can be ensured, and light leakage due to a gap between the light-emitting surface 123 and the skin to be treated can be avoided.

[0163] Exemplarily, the height by which the rotating member body 61 protrudes from the outer surface of the housing 100 can be 0.21 millimeters, 0.23 millimeters, 0.3 millimeters, 0.35 millimeters, 0.4 millimeters, 0.411 millimeters, 0.467 millimeters, 0.5 millimeters, 0.57 millimeters, 0.6 millimeters, 0.605 millimeters, 0.631 millimeters, 0.65 millimeters, 0.7 millimeters, 0.75 millimeters, 0.8 millimeters, 0.85 millimeters, 0.897 millimeters, 0.9 millimeters, 0.95 millimeters, 1 millimeter, 1.5 millimeters or 1.2 millimeters. The embodiments of the present utility model do not make any limitation thereto.

[0164] In some embodiments, the number of the rotating members 600 is at least two. The rotating members 600 are arranged to extend along the length direction of the light-emitting area 121, and the rotating members 600 are provided on each side of the light-emitting area 121 along the width direction.

[0165] Thus, by contacting the skin to be treated with at least two rotating members 600, the friction between the skin care device and the skin can be effectively reduced. At the same time, since the rotating members 600 are provided on each side of the light-emitting area 121 along the width direction, the force on each part of the light-emitting surface 123 can be made more uniform during the movement of the skin care device, so that the skin care device can move more stably and reliably.

[0166] In some embodiments, the length of the rotating member 600 is greater than or equal to the length of the light-emitting area 121, so as to ensure that the rotating member 600 has a large enough area to contact the skin to be treated, and thus effectively reduce the friction between the skin care device and the skin.

[0167] In some embodiments, the diameter of the rotating member body 61 gradually decreases from the middle to both ends. It can be understood that since the skin itself has a certain elasticity, when the rotating member 600 and the light-emitting surface 123 are abutted against the skin to be treated, the skin to be treated will be squeezed to form an arc-shaped pit. At this time, the structure of the rotating member body 61 with a thick middle and thin ends can well match the arc-shaped pit, so as to improve the user experience.

[0168] In some embodiments, the rotating member 600 is further configured to be telescopically disposed through the housing 100 so that the height of the rotating member 600 protruding from the light-emitting surface 123 is adjustable. It can be understood that the elasticity of the skin of different users is different. Therefore, when the skin care device is placed on the skin to be treated, the degree and shape of the depression of the user's skin are also different. At this time, the height of the rotating member 600 protruding from the outside of the light-emitting area 121 can be adaptively adjusted so that both the rotating member 600 and the light-emitting surface 123 are in contact with the skin, thereby ensuring the skin care effect and avoiding light leakage due to the gap between the light-emitting surface 123 and the skin to be treated.

[0169] Please continue to refer to Figure 18 , Figure 18 which is the first structural schematic diagram of the first elastic member of the embodiment of the present invention. In some embodiments, the skin care device may include a first elastic member 71. The first elastic member 71 is disposed in the housing 100 and is used to drive the rotating member 600 to move in a direction extending outside the light-emitting area 121. Thus, through the adaptive deformation of the first elastic member 71, the height of the rotating member 600 protruding from the light-emitting surface 123 can be automatically adjusted so that the light-emitting surface 123 of the housing 100 is in contact with the skin.

[0170] Exemplarily, the inner surface of the housing 100 includes a first arc surface 1241 located inside the light-emitting surface 123, and the rotating member 600 abuts against the first arc surface 1241. The first elastic member 71 is compressively disposed on the side of the rotating member 600 facing away from the first arc surface 1241 to drive the rotating member 600 to abut against the first arc surface 1241. Thus, the rotating member 600 can be rotatably mounted between the first arc surface 1241 and the first elastic member 71. When the skin care device abuts against the skin to be treated, the rotating member 600 can be pushed inwards by the skin to compress the first elastic member 71; when the skin care device is separated from the skin, the first elastic member 71 elastically resumes to drive the rotating member 600 to extend and reset.

[0171] It can also be understood that since the rotating member 600 abuts against the first arc surface 1241, the first arc surface 1241 can provide a good limiting effect on the rotating member 600 during the telescopic process of the rotating member 600.

[0172] In some embodiments, the radius of curvature of the first arc surface 1241 may be equal to the radius of the mounting shaft 62. Optionally, the radius of curvature of the first arc surface 1241 may also be greater than the radius of the mounting shaft 62, and the embodiment of the present invention does not limit this. When the radius of curvature of the first arc surface 1241 is greater than the radius of the mounting shaft 62, the mounting shaft 62 can abut against different positions of the first arc surface 1241, thereby simultaneously adjusting the height of the rotating member body 61 protruding from the light-emitting surface 123 and the side surface 125.

[0173] As mentioned above, in some embodiments, the housing 100 may be provided with a mounting hole 122 and a mounting groove 124 therethrough. The rotating member body 61 is inserted through the mounting hole 122 so as to partially protrude outside the light-emitting area 121. The mounting groove 124 communicates with the mounting hole 122, and the mounting shaft 62 is rotatably mounted in the mounting groove 124. Then, the groove wall of the mounting groove 124 may form a first arc surface 1241.

[0174] In some embodiments, the first elastic member 71 may include a first elastic element 711 and a first floating member 712. The first floating member 712 is disposed on a side of the first elastic element 711 close to the rotating member 600 and abuts against a side of the rotating member 600 facing away from the first arc surface 1241. Thus, a more stable and reliable contact can be formed between the first floating member 712 and the rotating member 600.

[0175] The surface of the first floating member 712 in contact with the rotating member 600 is a flat surface, so that a line contact is formed between the first elastic member 71 and the rotating member 600. Further, it is possible to avoid an excessive contact area between the first floating member 712 and the rotating member 600, resulting in excessive frictional force.

[0176] Optionally, the surface of the first floating member 712 in contact with the rotating member 600 may also be an arc surface, and the embodiments of the present invention do not limit this.

[0177] It can also be understood that the first elastic member 71 may also abut against the rotating member body 61 or may abut against the mounting shaft 62, and the embodiments of the present invention do not limit this.

[0178] The number of the first elastic members 71 is at least two, and each end of the rotating member 600 in the length direction cooperates with a first elastic member 71, so that the installation of the rotating member 600 is more stable and reliable.

[0179] For example, the number of the mounting shafts 62 is two, and the number of the first elastic members 71 may be at least two. Each mounting shaft 62 abuts against a first elastic member 71, so that the installation of the rotating member 600 is more stable and reliable.

[0180] In some embodiments, the first elastic member 71 includes at least one of a torsion spring and a helical compression spring. Of course, in some other embodiments, the first elastic member 71 may also include a disc spring, a leaf spring, etc., and the embodiments of the present invention do not limit this.

[0181] Please continue to refer to Figure 19 and Figure 20 , Figure 19 which is a schematic diagram of an installation structure of the rotating member according to an embodiment of the present invention. Figure 20For Figure 19 is an exploded view. In some embodiments, the skin care device may include a bracket assembly 34. The bracket assembly 34 is disposed within the housing 100 and is used to fix at least one of the cold compress assembly 400 and the light emitting assembly 200. It should be noted here that the bracket assembly 34 may be provided with at least one of the above-mentioned first air duct 3412 and second air duct 3413, or may not be provided with the above-mentioned first air duct 3412 and second air duct 3413. The embodiments of the present invention do not limit this. Among them, the first elastic member 71 may be installed on the bracket assembly 34 or on the inner surface of the housing 100. The embodiments of the present invention do not limit this.

[0182] Exemplarily, the bracket assembly 34 is provided with a mounting post 3431. The first elastic member 71 may include a torsion spring that is sleeved on the mounting post 3431 and abuts against the rotating member 600.

[0183] In some embodiments, reinforcing ribs 3432 are provided on the outer peripheral side of the mounting post 3431. The first elastic member 71 includes a torsion spring that is sleeved on the mounting post 3431. One torsion arm of the torsion spring presses against the reinforcing rib 3432, and the other torsion arm of the torsion spring presses against the rotating member 600 (such as the mounting shaft 62 of the rotating member 600), so that the rotating member 600 can be pushed in the direction of protruding from the housing 100 through the torsion spring.

[0184] In some embodiments, the rotating member 600 is detachably mounted on the housing 100, so that it is convenient for the user to disassemble the rotating member 600 for cleaning, replacement and other maintenance.

[0185] Please refer to Figure 21 , Figure 21 For Figure 19 is another perspective structural schematic diagram. Exemplarily, the housing 100 is further provided with a mounting hole 122 at least partially located on the light emitting surface 123. The skin care device further includes a second elastic member 72. The second elastic member 72 is at least partially disposed at the mounting hole 122 so that the rotating member 600 protrudes partially from the light emitting surface 123, so that it can roll on the skin to be treated. The rotating member 600 is rotatably inserted through the mounting hole 122, and at least one end of the rotating member 600 in the axial direction abuts against the second elastic member 72, so that the rotating member 600 can compress the second elastic member 72 and move axially to the disassembly state. When the rotating member 600 moves to the disassembly state, the rotating member 600 can be detached from the mounting hole 122 to the outside of the housing 100.

[0186] Exemplarily, as mentioned above, the rotating member 600 may include a rotating member body 61 and a mounting shaft 62. The rotating member body 61 is disposed through the housing 100 to partially protrude outside the light exiting area 121. The mounting shaft 62 is connected to the rotating member body 61, and the mounting shaft 62 is rotatably mounted on the housing 100.

[0187] Then, the installation shaft 62 can be arranged inside the housing 100, and the end surface of at least one installation shaft 62 abuts against the second elastic component 72. When the rotating member 600 moves to the disassembly state, the installation shaft 62 opposite to the compressed second elastic component 72 is exposed at the installation hole 122, so that it is allowed to be taken out from the installation hole 122 to the outside of the housing 100.

[0188] For example, a mounting shaft 62 is provided at each end of the rotating member body 61 along the left and right directions, and the opening of the mounting hole 122 is arranged upward, then one disassembly process of the rotating member 600 can be as follows:

[0189] First, push the rotating member body 61 to the right so that the installation shaft 62 at the left end of the rotating member body 61 moves to leak out of the installation hole 122; then, move the installation shaft 62 at the left end of the rotating member body 61 upward so that the installation shaft 62 at the left end of the rotating member body 61 moves to the outside of the shell 100; finally, take out the rotating member body 61 obliquely in the upper left direction so that the installation shaft 62 at the right end of the rotating member body 61 also detaches from the shell 100, thereby completing the disassembly of the rotating member 600, and vice versa, the installation of the rotating member 600 can be completed.

[0190] In some embodiments, each end of the rotating member 600 (i.e., the mounting shaft 62 at each end of the rotating member body 61) is abutted against a second elastic component 72, so that during the actual disassembly process, the user can first move the rotating member 600 along any side of the axial direction to complete the disassembly, thereby making the disassembly of the rotating member 600 more convenient.

[0191] In some embodiments, the rotating member body 61 is provided with an anti-skid structure, and the anti-skid structure is at least partially located outside the housing 100. Therefore, when the user moves the rotating member body 61 axially, the anti-skid structure can increase the friction between the user and the rotating member body 61, so that the user can move the rotating member body 61 more easily.

[0192] Exemplarily, the anti-skid structure may include anti-skid stripes arranged circumferentially around the rotating member body 61. Optionally, the anti-skid structure may also include a silicone member sleeved on the rotating member body 61, which is not limited in the embodiment of the utility model.

[0193] In some embodiments, the second elastic member 72 includes a second elastic element 721 and a second floating member 722. The second floating member 722 is disposed on a side of the second elastic element 721 close to the rotating member 600 and abuts against an end face of the mounting shaft 62.

[0194] The second elastic element 721 may include at least one of a helical compression spring, a disc spring, and a leaf spring.

[0195] For example, a vertical plate 126 protrudes from an inner surface of the housing 100. The vertical plate 126 is disposed perpendicular to an axial direction of the rotating member 600. The second elastic element 721 is a helical compression spring and is disposed to extend along the axial direction of the rotating member 600. The second elastic element 721 is compressively disposed between the vertical plate 126 and the second floating member 722.

[0196] In some embodiments, the skin care device includes a first elastic member 71. The first elastic member 71 is configured to push a circumferential surface of the mounting shaft 62 against an inner surface of the housing 100 to form a rotational fit. Thus, the first elastic member 71 can drive the rotating member 600 to move in a direction extending outside the light-emitting area 121. Then, continuing with the example where mounting shafts 62 are provided at each end of the rotating member body 61 in the left-right direction and the opening of the mounting hole 122 faces upward, one disassembly process of the rotating member 600 may be as follows:

[0197] First, push the rotating member body 61 to the right so that the mounting shaft 62 at the left end of the rotating member body 61 moves out of the mounting hole 122. At this time, the second elastic member 72 at the right end of the rotating member body 61 is compressed. Then, move the mounting shaft 62 at the left end of the rotating member body 61 upward so that the mounting shaft 62 at the left end of the rotating member body 61 moves outside the housing 100. At this time, the mounting shaft 62 at the right end of the rotating member body 61 moves downward accordingly, and the first elastic member 71 at the right end of the rotating member body 61 is compressed so that the rotating member 600 is inclined with the left end upward and the right end downward; finally, take out the rotating member body 61 obliquely in the upper-left direction so that the mounting shaft 62 at the right end of the rotating member body 61 also disengages from the housing 100, thereby completing the disassembly of the rotating member 600. Conversely, the installation of the rotating member 600 can be completed.

[0198] In some embodiments, an end of the first elastic member 71 close to the mounting shaft 62 is located on a side of the second floating member 722 close to the mounting shaft 62. Thus, during use, it can be avoided that when the first elastic member 71 is elastically restored after being compressed, it interferes with the second elastic member 72 and cannot tightly press the rotating member 600.

[0199] Exemplarily, as mentioned above, the first elastic member 71 includes a first elastic part 711 and a first floating part 712. The first floating part 712 is disposed on a side of the first elastic part 711 close to the rotating member 600 and abuts against the circumferential surface of the rotating member 600. The second elastic member 72 includes a second elastic part 721 and a second floating part 722. The second floating part 722 is disposed on a side of the second elastic part 721 close to the rotating member 600 and abuts against the end face of the mounting shaft 62. At this time, along the axial direction of the rotating member body 61, the orthographic projection of the first floating part 712 and at least a part of the orthographic projection of the first elastic part 711 are both located within the orthographic projection of the second floating part 722.

[0200] In some embodiments, the skin care device further includes a fitting detection module. The fitting detection module is disposed in the housing 100 and is used to detect the fitting state between the light-emitting surface 123 and the skin to be treated. The fitting contact module may include a skin fitting detection circuit, and the skin fitting detection circuit may adopt any one of the existing fitting detection circuits, which is not limited in the embodiments of the present invention.

[0201] It can be understood that since a part of the rotating member 600 protrudes from the light-emitting surface 123, after the rotating member 600 abuts against the skin to be treated, there is likely to be a gap between the light-emitting surface 123 and the skin to be treated. At this time, not only is it easy to cause light leakage from the gap between the light-emitting surface 123 and the skin to be treated, but also the care effect of the skin care device is likely to be reduced. Based on this, in the embodiments of the present application, when the fitting detection module detects that the skin care device is not fitted with the skin to be treated, the skin care device can perform corresponding processing actions, such as controlling the light-emitting assembly 200 to stop emitting light, prompting the user that there is no fit, etc., which is not limited in the embodiments of the present application.

[0202] In some embodiments, the fitting detection module may be electrically connected to the rotating member 600 to detect the fitting state between the skin care device and the skin to be treated through the rotating member 600. Therefore, it can also be understood that the rotating member 600 is reused as the detection electrode of the fitting detection module to reduce the components required to be provided on the light-emitting surface 123, so that the area of the light-emitting surface 123 can be reduced, facilitating the user to conveniently and accurately fit the light-emitting area 121 to the skin to be treated.

[0203] Exemplarily, the rotating member 600 is a conductive member to form a detection electrode.

[0204] For example, the rotating member 600 may be entirely made of metal or any other conductive material. Therefore, even if there is a certain wear on the surface of the rotating member 600, it will not affect the stability and reliability of the electrical connection of the rotating member 600.

[0205] Optionally, the rotating member 600 includes a conductive layer, and the conductive layer is electrically connected to the fitting detection module to form a detection electrode.

[0206] For example, the conductive layer may be formed on the rotating member 600 by means such as spraying, evaporation plating, electroplating, etc., and the embodiments of the present application do not limit this. Then, in the actual preparation process, only the conductive layer may adopt a conductive material, and the rotating member body 61 may be made of any material with characteristics such as low cost, easy to manufacture, wear-resistant, etc. according to actual needs.

[0207] Optionally, the rotating member 600 includes a conductive sheet, and the conductive sheet is electrically connected to the fitting detection module to form a detection electrode.

[0208] For example, the conductive sheet may be arranged on the rotating member 600 by means such as clamping, screwing, welding, etc., and the embodiments of the present application do not limit this. Then, in the actual preparation process, only the conductive sheet may adopt a conductive material, and the rotating member body 61 may be made of any material with characteristics such as low cost, easy to manufacture, wear-resistant, etc. according to actual needs.

[0209] In some embodiments, the skin care device further includes a first elastic member 71, and the first elastic member 71 is made of a conductive material. The first elastic member 71 is electrically connected to the fitting detection module, and the first elastic member 71 also abuts against the rotating member 600 to form an electrical connection. Therefore, the fitting detection module can form an electrical connection with the rotating member 600 through the first elastic member 71 without interfering with the rotation of the rotating member 600. In addition, during the rotation of the rotating member 600, even if the rotating member 600 and / or the first elastic member 71 are worn to a certain extent, the first elastic member 71 can be driven by its own elastic force to abut tightly against the rotating member 600, thereby ensuring the reliability and stability of the electrical connection.

[0210] In some embodiments, the number of the first elastic members 71 and the rotating members 600 is at least two, and different rotating members 600 are electrically connected to the fitting detection module through different first elastic members 71, so that multiple detection electrodes can be formed through the multiple rotating members 600 to improve the accuracy and reliability of detection.

[0211] As Figure 20 shown, as mentioned above, in some embodiments, the skin care device may include a bracket assembly 34. The bracket assembly 34 is arranged in the housing 100 and is used to fix at least one of the cold compress assembly 400 and the light emitting assembly 200. Among them, the first elastic member 71 may be installed on the bracket assembly 34 or on the inner surface of the housing 100, and the embodiments of the present application do not limit this.

[0212] Exemplarily, the bracket assembly 34 is provided with a mounting post 3431. The first elastic member 71 may include a torsion spring, and the torsion spring is sleeved on the mounting post 3431 and abuts against the rotating member 600.

[0213] In some embodiments, a reinforcing rib 3432 is provided on the outer circumference of the mounting post 3431. The first elastic component 71 includes a torsion spring, which is sleeved on the mounting post 3431, one torsion arm of the torsion spring is pressed against the reinforcing rib 3432 and is electrically connected to the fitting detection module, and the other torsion arm of the torsion spring is pressed against the rotating member 600, thereby realizing the electrical connection between the fitting detection module and the rotating member 600.

[0214] It can also be understood that the first elastic component 71 can be used to press the rotating member 600 against the inner surface of the shell 100, or can be used to press the rotating member 600 against other components inside the shell 100, and the embodiment of the present application is not limited to this.

[0215] Exemplarily, the skin care device further includes a first mounting plate 345. The first mounting plate 345 is mounted on the free end of the mounting post 3431 to limit the torsion spring (i.e., the first elastic component 71) from being separated from the mounting post 3431. The side of the rotating member 600 that is close to the light emitting area 121 in the circumferential direction is supported on the first mounting plate 345, and the side of the rotating member 600 that is away from the light emitting area 121 in the circumferential direction is abutted against the torsion spring, so that the rotating member 600 is rotatably disposed on the first mounting plate 345. Then, in the actual assembly process, the first elastic component 71, the first mounting plate 345 and the rotating member 600 can be pre-assembled on the bracket assembly 34 to facilitate integrated assembly and disassembly as a whole.

[0216] In some embodiments, the skin care device further comprises a second mounting plate 346. The second mounting plate 346 is mounted on the bracket assembly 34, and the second mounting plate 346 is sleeved on one end of the rotating member 600 away from the mounting column 3431 to form a rotating connection. Thus, both ends of the rotating member 600 can be supported and fixed, so that the rotation of the rotating member 600 is more stable and reliable.

[0217] It can also be understood that when the rotating member 600 is installed on the first mounting plate 345 and the second mounting plate 346 at the same time, and the first mounting plate 345 and the second mounting plate 346 are fixed to the bracket assembly 34, the first elastic component 71, the rotating member 600, the first mounting plate 345 and the second mounting plate 346 can be pre-assembled on the bracket assembly 34 to facilitate integrated disassembly and assembly as a whole.

[0218] The above are some examples of the rotating member 600 being reused as a detection electrode in the embodiment of the present application. It should be understood that when the rotating member 600 is not reused as a detection electrode, it can also be installed using the above structure, and the embodiment of the present application does not limit this.

[0219] Please continue to refer to Figure 22 , Figure 22 for Figure 10A partial enlarged view of another structure at position X. Optionally, the skin care device may further include a fitting detection component 800. The fitting detection component 800 is disposed at the light-emitting area 121 for collecting a fitting state signal of the light-emitting surface 123 and the skin to be treated.

[0220] In some embodiments, both the fitting detection component 800 and the rotating member 600 are at least partially disposed on the light-emitting surface 123. Thus, the rotating member 600 can contact the skin to be treated and roll on the skin to be treated. At the same time, the fitting detection component 800 can cooperate with the skin to be treated to collect a fitting state signal of the skin care device and the skin to be treated.

[0221] In some embodiments, the fitting detection component 800 can be electrically connected to a fitting detection circuit. The fitting detection circuit is used to obtain the fitting state of the light-emitting surface 123 and the skin to be treated based on the fitting state signal.

[0222] Exemplarily, the fitting detection component 800 includes at least one of a detection electrode, a proximity light sensor, a distance sensor, a temperature sensor, and a pressure sensor.

[0223] Then, when the fitting detection component 800 includes a detection electrode, the detection electrode can directly contact the skin care device to collect a fitting state signal of the skin care device and the skin to be treated, so that the fitting detection circuit can determine whether the light-emitting surface 123 is in contact with the skin to be treated.

[0224] When the fitting detection component 800 includes a proximity light sensor or a distance sensor, the photoelectric signals collected by the proximity light sensor and the distance sensor can be used as the above-mentioned fitting state signal, so that the fitting detection circuit can determine whether the light-emitting surface 123 is in contact with the skin to be treated.

[0225] When the fitting detection component 800 includes a temperature sensor, the body temperature signal detected by the temperature sensor can be used as the above-mentioned fitting state signal, so that the fitting detection circuit can determine whether the light-emitting surface 123 is in contact with the skin to be treated.

[0226] When the fitting detection component 800 includes a pressure sensor, the pressure temperature signal detected by the pressure sensor can be used as the above-mentioned fitting state signal, so that the fitting detection circuit can determine whether the light-emitting surface 123 is in contact with the skin to be treated.

[0227] In some embodiments, the number of the fitting detection components 800 is at least two, so that the detection accuracy and reliability can be improved by multiple fitting detection components 800.

[0228] Exemplarily, the number of the rotating members 600 and the fitting detection components 800 is at least two, and the rotating members 600 and the fitting detection components 800 are alternately arranged around the circumferential side of the light-emitting area 121.

[0229] Therefore, compared with the case where the fitting detection component 800 is located on the side of the rotating member 600 away from the light-emitting area 121, or the rotating member 600 is located on the side of the fitting detection component 800 away from the light-emitting area 121, in the embodiment of the present application, both the rotating member 600 and the fitting detection component 800 can be adjacent to the light-emitting area 121, so that the light-emitting surface 123 can be made smaller, facilitating the user to more accurately fit the light-emitting surface 123 to the skin to be treated.

[0230] In some embodiments, the number of the rotating members 600 is at least two, and the rotating members 600 are provided on each side of the light-emitting area 121 in the width direction. Thus, longer rotating members 600 can be provided on both sides in the width direction of the light-emitting area 121 to reduce the friction between the skin care device and the skin to be treated.

[0231] In some embodiments, the fitting detection components 800 are provided on each side of the light-emitting area 121 in the length direction. Thus, larger spaces can be reserved on both sides of the light-emitting area 121 in the width direction to provide longer rotating members 600, thereby reducing the friction between the skin care device and the skin to be treated.

[0232] In some embodiments, the skin care device may further include a prompting component, such as an indicator light, a display screen, a voice module, etc.

[0233] Exemplarily, the prompting component can be electrically connected to the fitting detection circuit and is used to indicate the fitting state between the skin care device and the skin to be treated. The prompting component includes at least one of an indicator light and a voice module, so as to remind the user to timely fit the light-emitting surface 123 of the skin care device to the skin to be treated to improve the care effect.

[0234] Please continue to refer to Figure 23 , Figure 23 which is a schematic structural diagram of the rotation detection component provided by the embodiment of the present application. In some embodiments, the skin care device further includes a rotation detection component 900. The rotation detection component 900 is disposed in the housing 100 and is used to detect the rotation speed and / or rotation angle of the rotating member 600. Thus, information such as the moving speed and distance of the skin care device on the skin to be treated can be conveniently determined according to the rotation speed and / or rotation angle of the rotating member 600.

[0235] In some embodiments, the skin care device may further include a controller, which is electrically connected to the rotation detection component 900 and the light-emitting component 200 respectively. The controller is configured to: control the operating state of the light-emitting component 200 based on the rotation information parameters of the rotating member 600, and the rotation information parameters include the rotation speed and / or rotation angle of the rotating member 600.

[0236] Exemplarily, the controller is configured to: determine the target light-emitting frequency of the light-emitting component 200 based on the rotation speed of the rotating member 600; set the current light-emitting frequency of the light-emitting component 200 to the target light-emitting frequency. Thus, the skin care device can emit light at a more appropriate frequency during the movement process to improve the skin care effect.

[0237] In some embodiments, the controller is configured to: whenever the rotating member 600 rotates a preset angle, control the light-emitting component 200 to emit light a preset number of times. Thereby, it is possible to avoid excessive light rays from the light-emitting component 200 hitting the same area of the skin to be treated.

[0238] As mentioned above, in some embodiments, the skin care device may further include a prompting component, such as an indicator light, a display screen, a voice module, etc. The controller may also be electrically connected to the prompting component. The controller is configured to: when the rotation speed of the rotating member 600 is greater than a preset value, control the prompting component to remind the user. Thus, it is possible to avoid the skin care device moving too fast, resulting in the light-emitting component 200 failing to care for the skin to be treated.

[0239] In some embodiments, the rotation detection component 900 may further include at least one of a photoelectric sensor, an encoder, and a Hall sensor, and the embodiments of the present application do not limit this.

[0240] For example, when the rotation detection component 900 includes a photoelectric sensor, the rotating member 600 may be provided with a trigger portion that cooperates with the photoelectric sensor, and the photoelectric sensor is arranged on the rotation path of the trigger portion. Thus, every time the rotating member 600 rotates a certain angle, the trigger portion can trigger the photoelectric sensor to detect the rotation angle and / or rotation speed of the rotating member 600.

[0241] When the rotation detection component 900 includes an encoder, the roller of the encoder may be abutted against the rotating member 600, so that the rotating member 600 can drive the roller of the encoder to rotate to detect the rotation angle and / or rotation speed of the rotating member 600.

[0242] Please continue to refer to Figure 24 , Figure 24 For Figure 23Exploded diagram of the embodiment. In some embodiments, the rotation detection component 900 may include a driven wheel 91 and a rotation sensor 92. The driven wheel 91 is rotatably mounted in the housing 100, and the driven wheel 91 is transmission-connected to the rotating member 600 so as to rotate along with the rotation of the rotating member 600. The rotation sensor 92 is disposed in the housing 100 and is used to detect the rotation speed and / or rotation angle of the driven wheel 91. Therefore, by adding the driven wheel 91, the rotation sensor 92 can be flexibly disposed at different positions in the housing 100, so as to facilitate the reasonable distribution of components inside the housing 100.

[0243] In some embodiments, the driven wheel 91 is provided with at least one magnetic member 911, and the rotation sensor 92 includes a Hall sensor to cooperate with the magnetic member 911 of the driven wheel 91 to detect the rotation speed and / or rotation angle of the rotating member 600, so that the rotation sensor 92 has the advantages of high sensitivity and stable signal output.

[0244] In some embodiments, there are multiple magnetic members 911, and the multiple magnetic members 911 are evenly spaced along the circumference of the driven wheel 91. Therefore, through the cooperation of the Hall sensor and the multiple magnetic members 911, the detection of multiple rotation angles of the multiple rotating members 600 can be achieved.

[0245] As mentioned above, the skin care device may further include a bracket assembly 34, which is disposed in the housing 100 and is equipped with at least one of the cold compress assembly 400 and the light output assembly 200. The rotation detection component 900 further includes a second mounting plate 346, which is mounted on the bracket assembly 34 or the housing 100. The rotation sensor 92 is mounted on the second mounting plate 346, and the driven wheel 91 is mounted between the second mounting plate 346 and the bracket assembly 34. Thus, by hiding the driven wheel 91 between the bracket assembly 34 and the driven wheel 91, a certain protection can be provided to the driven wheel 91 to prevent other components from interfering with the rotation of the driven wheel 91.

[0246] In some embodiments, one end of the rotating member 600 is rotatably mounted on the second mounting plate 346 , so that the installation of the rotating member 600 is more stable.

[0247] In some embodiments, the rotation detection component 900 further includes a first mounting pin 93. The first mounting pin 93 is disposed on the second mounting plate 346, and the driven wheel 91 is sleeved on the first mounting pin 93. Thus, both the rotating member 600 and the driven wheel 91 can be mounted on the second mounting plate 346 to reduce the shape and position tolerance between the driven wheel 91 and the rotating member 600.

[0248] In some embodiments, the rotation detection component 900 further includes a second mounting pin 94, and the second mounting pin 94 is disposed on the second mounting plate 346. The rotation detection component 900 further includes a transmission wheel 95 sleeved on the second mounting pin 94. The transmission wheel 95 is respectively connected to the rotating member 600 and the driven wheel 91 in transmission connection, so that the transmission wheel 95 can rotate with the rotating member 600 to drive the driven wheel 91 to rotate. Thus, by adding the transmission wheel 95, the driven wheel 91 can be flexibly disposed at different positions in the housing 100, so as to facilitate the reasonable distribution of components inside the housing 100.

[0249] Of course, the driven wheel 91 may also be in direct contact with the rotating member 600 to form a transmission connection, that is, the rotation detection component 900 may not include the above-mentioned transmission wheel 95, and the embodiment of the present application does not limit this.

[0250] Please continue to refer to Figure 25 , Figure 25 for Figure 24 Cross-sectional view of the skin care device shown Figure 4 In some embodiments, one side surface of the driven wheel 91 in the thickness direction is disposed opposite to the cold compress assembly 400 .

[0251] It is understandable that in order to improve the cold compress effect of the cold compress assembly 400, the volume of the cold compress assembly 400 is usually large. For example, as mentioned above, the cold compress assembly 400 may include a light guide component 41 and a cooling plate 42. To improve the cooling effect of the cooling plate 42, the light guide component 41 needs to be made larger to increase the contact area between the light guide component 41 and the cooling plate 42. Based on this, in the embodiment of the present application, one side surface of the thickness direction of the driven wheel 91 is arranged directly opposite to the cold compress assembly 400, so that the larger space on the outer peripheral side of the cold compress assembly 400 can be fully utilized to facilitate the miniaturized design of the skin care device.

[0252] In addition, since the cold compress component 400 is arranged in the light emitting area 121, the rotating part 600 is also located next to the light emitting area 121, and the driven wheel 91 is arranged opposite to the cold compress component 400, the distance between the driven wheel 91 and the rotating part 600 can be closer, thereby avoiding the transmission chain between the driven wheel 91 and the rotating part 600 being too long, and the accuracy of the detection result of the rotation detection component 900 can be improved.

[0253] In some embodiments, along the thickness direction of the driven wheel 91, at least 70% of the area of ​​the orthographic projection of the driven wheel 91 overlaps with the orthographic projection of the cold compress assembly 400, so that the larger space on the outer peripheral side of the cold compress assembly 400 can be fully utilized to facilitate the miniaturized design of the skin care device.

[0254] Exemplarily, along the thickness direction of the driven wheel 91, 70%, 74%, 75%, 78.3%, 80%, 82.70%, 85%, 90%, 92.7%, 95% or 100% of the orthographic projection area of the driven wheel 91 coincides with the orthographic projection of the cold compress assembly 400.

[0255] As mentioned above, the number of the second air ducts 3413 is two, and each second air duct 3413 is provided with a second heat sink 352. Then, the cold compress assembly 400, the driven wheel 91 and the first air duct 3412 can all be at least partially located between the two second air ducts 3413. The cold compress assembly 400 and the driven wheel 91 are arranged side by side on one side of the first air duct 3412 close to the light-emitting area 121, and one side surface in the thickness direction of the driven wheel 91 is arranged facing the cold compress assembly 400.

[0256] For example, the first air duct 3412 and the second air duct 3413 both extend in the left-right direction, and the two second air ducts 3413 can be arranged at intervals in the front-back direction. At this time, the cold compress assembly 400, the driven wheel 91 and the first air duct 3412 are all at least partially located between the two second air ducts 3413, and the driven wheel 91 and the cold compress assembly 400 are arranged in the left-right direction. Thereby, the layout among the first air duct 3412, the cold compress assembly 400 and the driven wheel 91 is compact, and the driven wheel 91 is prevented from blocking the first air duct 3412 and the second air duct 3413. On this basis, the space on both sides of the first air duct 3412, the cold compress assembly 400 and the driven wheel 91 can be fully utilized to set larger second air ducts 3413, thereby improving the heat dissipation effect.

[0257] In some embodiments, the first air duct 3412 and the second air duct 3413 both extend in the thickness direction of the driven wheel 91, and one end of the first air duct 3412 close to the fan 31 and one end of the second air duct 3413 close to the fan 31 are both located on the outer peripheral side of the driven wheel 91, so as to prevent the driven wheel 91 from blocking the first air duct 3412 and the second air duct 3413.

[0258] Please continue to refer to Figure 26 , Figure 26 , which is a schematic structural diagram of the diversion part of the embodiment of the present application. In some embodiments, at least a partial area of one side surface in the thickness direction of the driven wheel 91 is arranged facing the air outlet of the fan 31. A diversion part 3441 is provided on one side of the bracket assembly 34 close to the fan 31. The diversion part 3441 covers the part of the driven wheel 91 facing the fan 31 to direct the air blown by the fan 31 to the driven wheel 91 to at least one of the first air duct 3412 and the second air duct 3413. Thereby, the flow rate of the air blown to the corresponding first air duct 3412 and / or the second air duct 3413 can be increased through the diversion part 3441, so as to improve the heat dissipation effect at the corresponding first air duct 3412 and / or the second air duct 3413.

[0259] Exemplarily, as mentioned above, the bracket assembly 34 includes a first bracket 341. The first bracket 341 is disposed within the housing 100. The first bracket 341 includes a bottom plate 3414 and two side plates 3415. The bottom plate 3414 is disposed on the side of the light-emitting assembly 200 facing away from the light-emitting area 121. The two side plates 3415 are both connected to the side of the bottom plate 3414 close to the light-emitting area 121 and are spaced apart. A first air duct 3412 is formed between the bottom plate 3414 and the two side plates 3415. A second air duct 3413 is formed between one side of each of the side plates 3415 facing away from the first air duct 3412 and the housing 100.

[0260] Then, the bracket assembly 34 may further include a third bracket 343 and a fourth bracket 344. The third bracket 343 is connected to the side of the side plate 3415 close to the light-emitting area 121, and the cold compress assembly 400 is mounted on the third bracket 343. The second air duct 3413 is also partially formed between the third bracket 343 and the housing 100. The fourth bracket 344 is connected to the third bracket 343. One end of the fourth bracket 344 close to the blower 31 is located between the driven wheel 91 and the air outlet of the blower 31 to form a flow guiding portion 3441, and the flow guiding portion 3441 is configured to guide the air blown by the blower 31 to the driven wheel 91 to at least one of the first air duct 3412 and the second air duct 3413.

[0261] Thus, by splitting the bracket assembly 34 into the third bracket 343 and the fourth bracket 344 for separate molding, not only can the manufacturing difficulty of the bracket assembly 34 be reduced, but also the installation difficulty of the bracket assembly 34 and the rotation detection component 900 can be reduced. For example, the light-emitting assembly 200 and the third bracket 343 can be first mounted on the first bracket 341, then the rotation detection component 900 can be mounted on the third bracket 343, and finally the fourth bracket 344 can be mounted on the third bracket 343 to form the flow guiding portion 3441 covering the driven wheel 91.

[0262] It can also be understood that as mentioned above, the skin care device may further include a first mounting plate 345 and a second mounting plate 346, then the first mounting plate 345 and the second mounting plate 346 can be mounted and fixed on the third bracket 343.

[0263] In some embodiments, the number of the third brackets 343 may be two. Each third bracket 343 is respectively connected and fixed to a side plate 3415. A space for mounting the cold compress assembly 400 (such as the light guiding component 41 of the cold compress assembly 400) is formed between the two third brackets 343.

[0264] In some embodiments, the number of the fourth brackets 344 may be two. Each fourth bracket 344 is respectively connected and fixed to a third bracket 343.

[0265] As Figure 2 shown, in some embodiments, the skin care device may further include a filter component 1000. The filter component 1000 is disposed within the housing 100, and the filter component 1000 is located on the side of the light emitting component 200 facing the light emitting area 121, for filtering the light emitted by the light emitting component 200 towards the light emitting area 121.

[0266] In some embodiments, the filter component 1000 may be used to filter light with a wavelength less than or equal to 560 nanometers. It can be understood that the wavelengths of light required for the skin care device to perform photon rejuvenation and hair removal on the skin to be treated are generally between 460 nanometers and 1200 nanometers, and most of the light generated by the light emitting component 200 has a wavelength below 1200 nanometers. Therefore, the filter component 1000 can filter out the required light for hair removal and photon rejuvenation.

[0267] In some embodiments, the filter component 1000 may include at least two filter sheets, so as to improve the filtering effect through the at least two filter sheets.

[0268] In some embodiments, the skin care device further includes a driving component. The driving component is installed within the housing 100, and the driving component is in transmission connection with the rotating member 600, for driving the rotating member 600 to rotate.

[0269] Therefore, during use, the rotating member 600 can be driven to rotate by the driving component to control the movement of the skin care device on the skin to be treated.

[0270] It can also be understood that the skin care device may further include a controller, and the controller is electrically connected to the driving component and the light emitting component 200 respectively. The controller is configured to: control the working state of the light emitting component 200 based on the working information of the driving component, or control the working state of the driving component based on the working information of the light emitting component 200.

[0271] Exemplarily, the controller is configured to: determine the movement information parameters of the skin care device on the skin to be treated based on the working information of the driving component, and the movement information parameters may include at least one of movement speed, movement distance, and movement direction; control the working state of the light emitting component 200 based on the movement information parameters.

[0272] For example, when the controller determines that the skin care device has moved a certain distance, it controls the light emitting component 200 to emit light; or, the controller may control the light emitting frequency of the light emitting component 200 according to the movement speed of the skin care device, and the embodiments of the present application do not limit this.

[0273] In some embodiments, the controller is configured to: determine the movement information parameters of the driving component based on the working information of the light-emitting component 200, where the working information of the light-emitting component 200 may include at least one of the light-emitting frequency, light-emitting intensity, and light-emitting mode of the light-emitting component 200; the movement information parameters may include at least one of the movement speed, movement distance, and movement direction; and control the working state of the driving component based on the movement information parameters.

[0274] In some embodiments, the driving component may include a motor. Of course, the driving component may also include any other power source capable of driving the rotating member 600 to rotate, and the embodiments of the present application do not make any limitations in this regard.

[0275] The embodiments of the present application have been introduced in detail above. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
