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 scope of protection 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.

[0029] 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.

[0030] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of the skin care device according to the embodiment of the present utility model. 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 processed.

[0031] The skin care device further includes a heat dissipation assembly 300. The heat dissipation assembly 300 is disposed in the housing 100 to dissipate heat from the light emitting assembly 200.

[0032] Of course, the skin care device may further include a cold compress component 400. The cold compress component 400 is disposed on the housing 100 and is used to perform cold compress on 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 to dissipate heat from the light emitting component 200, or the heat dissipation component 300 may also be used to dissipate 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.

[0033] The above is an overall description of the skin care device in the embodiments of the present invention. Next, an example will be given in combination with the light emitting structure of the skin care device.

[0034] 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 irradiates the skin to be treated from the light emitting area 121. The cold compress component 400 may be disposed at the light emitting area 121 for performing cold compress on the skin to be treated.

[0035] 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, which 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), which is an IPL light source 21 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 21 component.

[0036] 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 transformation component to charge the capacitor. When the capacitor is charged to a preset value and the controller receives a 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 release intense pulsed light, thus completing one light emission.

[0037] Next, the technical solution of the embodiments of the present invention will be further described in combination with the cold compress component 400.

[0038] It should be noted first 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.

[0039] The cold compress component 400 is disposed at the light-emitting area 121. It can be that the cold compress component 400 is installed within the light-emitting area 121, or the cold compress component 400 is disposed on the periphery of the light-emitting area 121, or part of the cold compress component 400 is disposed within the light-emitting area 121 and part is disposed on the periphery of the light-emitting area 121. The embodiments of the present invention do not limit this. It should be noted that when the cold compress component 400 is installed within 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 this periphery, so as to indirectly perform cold compress on the skin to be treated.

[0040] For example, the cold compress component 400 may include a light guide member 41 and a Peltier device 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 Peltier device 42 is thermally connected to the light guide member 41. For example, the Peltier device 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.

[0041] Furthermore, the Peltier device 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 come into contact with the skin. Thus, 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 be cooled by the Peltier device 42 to provide cold compress for the user.

[0042] Specifically, the Peltier device 42 is also called a thermoelectric cooler. 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.

[0043] The light guide member 41 can be made of sapphire or other light guide materials. The embodiments of the present invention do not limit this.

[0044] In an alternative embodiment, the cold compress component 400 may further include a cold compress member (not shown in the figure) and a Peltier device 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 face of the light-emitting area 121. The Peltier device 42 is thermally connected to the cold compress member; for example, the Peltier device 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.

[0045] Furthermore, the Peltier device 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 come into contact with the skin to provide cold compress for the user.

[0046] For example, the cold compress member can be an annular metal member disposed around the light-emitting area 121 or the like.

[0047] 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 refrigeration liquid or a refrigeration gas) that can flow in the flow cavity, and a driving device (such as a compressor, etc.) for driving the refrigeration medium to circulate, so that 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.

[0048] In some embodiments, the heat dissipation assembly 300 can include a fan, and the fan is disposed inside the housing 100 and is used to drive the air convection inside and outside the housing 100, so as to dissipate heat from the cold compress assembly 400 and / or the light-emitting assembly 200.

[0049] The light-emitting area 121 can be formed on the end surface of one end of the housing 100 in the length direction, or can be formed on the circumferential side surface of one end of the housing 100 in the length direction. The embodiments of the present invention do not limit this.

[0050] For example, the housing 100 includes a main housing 11 and a head housing 12. The main housing 11 is in a long strip shape to form the main structure of the housing 100. The head housing 12 is disposed on the circumferential side of the main housing 11, and the light-emitting area 121 is provided on the end surface of the side of the head housing 12 facing away from the main housing 11.

[0051] Next, continue to give examples in combination with other structures of the skin care device.

[0052] Please continue to refer to Figure 2 , Figure 2 is Figure 1 a schematic structural diagram of a rotating member of the skin care device 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 can further include a rotating member 600, and the rotating member 600 is rotatably mounted 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.

[0053] Then, taking the example of a user caring for multiple areas to be treated on the arm, the user can first abut the rotating member 600 against the arm, and then drive the housing 100 or the skin care device to move between multiple areas to be treated by rolling the rotating member 600 on the skin, so that the light-emitting assembly 200 can complete 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 abrasions, 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 movement path, thereby improving the skin care efficiency.

[0054] 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.

[0055] Please continue to refer to Figure 3 , Figure 3 For Figure 2 the schematic diagram of the cooperation structure between 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 mounted on the housing 100.

[0056] It should be noted that the mounting shaft 62 being rotatably mounted on the housing 100 may be that the mounting shaft 62 directly contacts the housing 100 to form a rotational connection, or the mounting shaft 62 is 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.

[0057] The rotating member body 61 may be columnar or spherical. When the rotating member body 61 is columnar, the mounting shaft 62 may be connected to the end of the rotating member body 61. The embodiments of the present invention do not limit this.

[0058] Taking the rotating member body 61 being columnar as an example, mounting shafts 62 are provided at each end of the rotating member body 61. Optionally, the rotating member body 61 may 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 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.

[0059] In some embodiments, the mounting shaft 62 can be prismatic, 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 skin surface to be treated.

[0060] 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 skin surface to be treated.

[0061] Please continue to refer to Figure 4 , Figure 4 For Figure 3 another schematic structural view 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. Thus, 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 skin surface to be treated.

[0062] Please continue to refer to Figure 5 and Figure 6 , Figure 5 For Figure 3 the exploded view of Figure 6 For Figure 2 the partial enlarged view at X of . 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 penetrating therethrough, and the mounting hole 122 is at least partially located on the light-emitting surface 123. The mounting hole 122 is adjacent to the light-emitting area 121, and the rotating member body 61 is inserted through the mounting hole 122 to partially protrude from the light-emitting surface 123.

[0063] It can be understood that by arranging 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 also be made closer, so as to avoid the need to set a larger area for the light-emitting surface 123 of the housing 100 to arrange the mounting hole 122 and the light-emitting area 121 with a larger spacing. Furthermore, during use, the user can more conveniently and accurately attach the light-emitting area 121 to the skin to be treated.

[0064] In some embodiments, an installation groove 124 is further provided on the inner wall of the housing 100. The installation groove 124 communicates with the installation hole 122. The installation shaft 62 is rotatably arranged in the installation groove 124. Thus, by hiding the connection part between the rotating member 600 and the housing 100 inside the housing 100, it is possible to prevent the rotating member body 61 from being exposed at the connection with the housing 100 and being accidentally damaged, and further improve the stability and reliability of the installation of the rotating member 600.

[0065] 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 rotating member 600 protrudes partially from the light-emitting surface 123 and partially from the side surface 125. For example, the installation 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.

[0066] 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 part of the side surface 125 will be accommodated 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, so that the rotating member 600 rolls more smoothly on the skin to be treated, thereby improving the user experience.

[0067] In some embodiments, the height by which the rotating member 600 (for example, 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 prevent the rotating member body 61 from protruding too much from the outer surface of the housing 100 and causing the light-emitting surface 123 to fail to fit the skin to be treated, thereby ensuring both the skin care effect and avoiding light leakage due to a gap between the light-emitting surface 123 and the skin to be treated.

[0068] 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 invention do not limit this.

[0069] 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.

[0070] 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.

[0071] 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, thereby effectively reducing the friction between the skin care device and the skin.

[0072] In some embodiments, the diameter of the part of the rotating member 600 protruding outside the housing 100 (such as 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 abut against the skin to be treated, the skin to be treated will be squeezed to form an arc-shaped concave 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 concave pit to improve the user experience.

[0073] In some embodiments, the rotating member 600 is also 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, so when the user places the skin care device 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 outside the light-emitting area 121 can be adaptively adjusted so that the rotating member 600 and the light-emitting surface 123 are both in contact with the skin, thereby ensuring the skin care effect and avoiding light leakage due to a gap between the light-emitting surface 123 and the skin to be treated.

[0074] Please continue to refer to Figure 7 , Figure 7This is the first structural schematic diagram of the first elastic component in the embodiment of the present utility model. In some embodiments, the skin care device may include a first elastic component 71. The first elastic component 71 is disposed within the housing 100 and is configured to drive the rotating member 600 to move in a direction extending out of the light-emitting surface 123. Thus, through the adaptive deformation of the first elastic component 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 fits against the skin.

[0075] 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 component 71 is compressively disposed on a 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 component 71. When the skin care device abuts against the skin to be treated, the rotating member 600 can be pressed inward by the skin to compress the first elastic component 71; when the skin care device is separated from the skin, the first elastic component 71 elastically resumes to drive the rotating member 600 to extend and reset.

[0076] It can also be understood that since the rotating member 600 abuts against the first arc surface 1241, during the telescoping process of the rotating member 600, the first arc surface 1241 can provide a good limiting effect on the rotating member 600.

[0077] 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 embodiments of the present utility model do 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.

[0078] 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 passes through the mounting hole 122 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 the first arc surface 1241.

[0079] In some embodiments, the first elastic member 71 may include a first elastic member 711 and a first floating member 712. The first floating member 712 is disposed on a side of the first elastic member 711 close to the rotating member 600 and abuts against a side of the rotating member 600 away from the first arc surface 1241. Thus, a more stable and reliable contact can be formed with the rotating member 600 through the first floating member 712.

[0080] The surface of the first floating member 712 abutting against the rotating member 600 is a plane, so that the first elastic member 71 forms a line contact with the rotating member 600. Thus, it is possible to avoid excessive friction due to excessive contact area between the first floating member 712 and the rotating member 600.

[0081] Optionally, the surface of one side of the first floating member 712 abutting against the rotating member 600 may also be a curved surface, which is not limited in the embodiment of the present utility model.

[0082] It can also be understood that the first elastic component 71 can also abut against the rotating member body 61 or the mounting shaft 62, and the embodiment of the utility model is not limited to this.

[0083] There are at least two first elastic components 71 , and each end of the rotating member 600 in the length direction cooperates with a first elastic component 71 , so that the installation of the rotating member 600 is more stable and reliable.

[0084] For example, the number of the installation shafts 62 is two, the number of the first elastic components 71 may be at least two, and each installation shaft 62 is in contact with a first elastic component 71, so that the installation of the rotating member 600 is more stable and reliable.

[0085] Please continue to refer to Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of an installation structure of a rotating member of an embodiment of the utility model. Figure 9 for Figure 8 In some embodiments, the first elastic component 71 includes at least one of a torsion spring and a helical compression spring. Of course, in some other embodiments, the first elastic component 71 may also include a disc spring, a leaf spring, etc., which is not limited in the embodiment of the utility model.

[0086] In some embodiments, the skin care device may include a bracket assembly 34. The bracket assembly 34 is disposed in the housing 100 and is used to fix at least one of the cold compress assembly 400 and the light output assembly 200. The first elastic component 71 may be mounted on the bracket assembly 34 or on the inner surface of the housing 100, which is not limited in the embodiment of the utility model.

[0087] Exemplarily, the bracket assembly 34 is provided with a mounting post 3431. The first elastic member 71 may include a torsion spring which is sleeved on the mounting post 3431 and abuts against the rotating member 600.

[0088] 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 which 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.

[0089] 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 maintenance such as cleaning and replacement.

[0090] Please continue to refer to Figure 10 , Figure 10 For Figure 7 the schematic structural view of another perspective of the first elastic member shown. 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. The rotating member 600 is rotatably passed through the mounting hole 122 so that a part of the rotating member 600 protrudes from the light-emitting surface 123, so as to be able to roll on the skin to be treated. 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 thus move axially to the disassembly state. When the rotating member 600 moves to the disassembly state, the rotating member 600 can be disengaged from the mounting hole 122 to the outside of the housing 100.

[0091] 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 passed through the housing 100 to partially protrude outside the light-emitting 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.

[0092] Then, the mounting shaft 62 may be disposed inside the housing 100, and the end face of at least one mounting shaft 62 abuts against the second elastic member 72. When the rotating member 600 moves to the disassembly state, the mounting shaft 62 opposite to the compressed second elastic member 72 is exposed at the mounting hole 122, so that it is allowed to be taken out of the mounting hole 122 to the outside of the housing 100.

[0093] For example, if the 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 is upward, then one disassembly process of the rotating member 600 may be as follows:

[0094] 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; 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 to the outside of the housing 100; finally, tilt and remove the rotating member body 61 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.

[0095] In some embodiments, a second elastic member 72 abuts against each end of the rotating member 600 (i.e., the mounting shaft 62 at each end of the rotating member body 61). Thus, during the actual disassembly process, the user can first move the rotating member 600 by any side in the axial direction to complete the disassembly, making the disassembly of the rotating member 600 more convenient.

[0096] In some embodiments, the rotating member body 61 is provided with an anti-slip structure, and at least part of the anti-slip structure is located outside the housing 100. Therefore, during the process of the user moving the rotating member body 61 in the axial direction, the anti-slip structure can increase the friction between the user and the rotating member body 61, enabling the user to move the rotating member body 61 more easily.

[0097] Exemplarily, the anti-slip structure may include anti-slip stripes circumferentially arranged around the rotating member body 61. Optionally, the anti-slip structure may further include a silicone member sleeved on the rotating member body 61. The embodiments of the present invention do not limit this.

[0098] In some embodiments, the second elastic member 72 includes a second elastic member 721 and a second floating member 722. The second floating member 722 is disposed on the side of the second elastic member 721 close to the rotating member 600 and abuts against the end face of the mounting shaft 62.

[0099] The second elastic member 721 may include at least one of a helical compression spring, a disc spring, and a leaf spring.

[0100] For example, a vertical plate 126 protrudes from the inner surface of the housing 100. The vertical plate 126 is perpendicular to the axial direction of the rotating member 600. The second elastic member 721 is a helical compression spring and extends along the axial direction of the rotating member 600. The second elastic member 721 is compressively disposed between the vertical plate 126 and the second floating member 722.

[0101] In some embodiments, the skin care device includes a first elastic member 71. The first elastic member 71 is configured to press the circumferential surface of the mounting shaft 62 against the 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 the 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 can be as follows:

[0102] 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, and 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.

[0103] In some embodiments, one end of the first elastic member 71 close to the mounting shaft 62 is located on the 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 compressed and then elastically restored, it interferes with the second elastic member 72 and cannot tightly press the rotating member 600.

[0104] Exemplarily, as mentioned above, the first elastic member 71 includes a first elastic element 711 and a first floating member 712. The first floating member 712 is disposed on the side of the first elastic element 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 element 721 and a second floating member 722. The second floating member 722 is disposed on the side of the second elastic element 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 member 712 and at least a part of the orthographic projection of the first elastic element 711 are both located within the orthographic projection of the second floating member 722.

[0105] In some embodiments, the skin care device further includes a fitting detection module. The fitting detection module is disposed within the housing 100 and is configured 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 fitting detection circuits in the prior art, and the embodiments of the present invention do not limit this.

[0106] 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 for the gap between the light-emitting surface 123 and the skin to be treated to leak light, but also the care effect of the skin care device is likely to be reduced. Based on this, in the embodiments of the present invention, when the fitting detection module detects that the skin care device is not in contact 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 contact, etc., and the embodiments of the present invention do not limit this.

[0107] 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.

[0108] Exemplarily, the rotating member 600 is a conductive member to form a detection electrode.

[0109] For example, the rotating member 600 may be entirely made of metal or any other conductive material. Therefore, even if there is a certain amount of 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.

[0110] 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.

[0111] For example, the conductive layer may be formed on the rotating member 600 by means of spraying, evaporation plating, electroplating, etc., and the embodiments of the present invention do not limit this. Then, in the actual preparation process, only the conductive layer may be made of a conductive material, and the rotating member body 61 may be selected according to actual needs to have any characteristics such as low cost, easy manufacturability, wear resistance, etc.

[0112] 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.

[0113] For example, the conductive sheet can be arranged on the rotating member 600 by means of snap connection, screw connection, welding, etc., and the embodiments of the present invention do not limit this. Then, in the actual preparation process, only the conductive sheet can be made of a conductive material, and the rotating member body 61 can be made of any material with characteristics such as low cost, easy to manufacture, wear-resistant, etc. according to actual needs.

[0114] 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 pressed tightly against the rotating member 600 under the drive of its own elastic force, so as to ensure the reliability and stability of the electrical connection.

[0115] 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 multiple rotating members 600 to improve the accuracy and reliability of detection.

[0116] Exemplarily, as Figure 8 shown, as mentioned above, the skin care device can 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 can be installed on the bracket assembly 34 or on the inner surface of the housing 100, and the embodiments of the present invention do not limit this.

[0117] For example, the bracket assembly 34 is provided with a mounting post 3431. The first elastic member 71 can include a torsion spring, and the torsion spring is sleeved on the mounting post 3431 and abuts against the rotating member 600.

[0118] In some embodiments, a reinforcing rib 3432 is provided on the outer peripheral side of the mounting post 3431. The first elastic member 71 includes a torsion spring, the torsion spring 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, so as to realize the electrical connection between the fitting detection module and the rotating member 600.

[0119] It can also be understood that the first elastic member 71 can press the rotating member 600 against the inner surface of the housing 100, or it can press the rotating member 600 against other components inside the housing 100. The embodiments of the present invention do not limit this.

[0120] 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 prevent the torsion spring (i.e., the first elastic member 71) from detaching from the mounting post 3431. One side of the rotating member 600 in the circumferential direction close to the light-emitting area 121 is supported by the first mounting plate 345, and the side of the rotating member 600 in the circumferential direction away from the light-emitting area 121 abuts against the torsion spring, so that the rotating member 600 is rotatably arranged on the first mounting plate 345. Then, during the actual assembly process, the first elastic member 71, the first mounting plate 345, and the rotating member 600 can be pre-assembled on the bracket assembly 34 to facilitate integrated disassembly and assembly as a whole.

[0121] In some embodiments, the skin care device further includes 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 post 3431 to form a rotational connection. Thus, both ends of the rotating member 600 can be supported and fixed, making the rotation of the rotating member 600 more stable and reliable.

[0122] It can also be understood that when the rotating member 600 is simultaneously mounted on the first mounting plate 345 and the second mounting plate 346, and the first mounting plate 345 and the second mounting plate 346 are fixed to the bracket assembly 34, the first elastic member 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.

[0123] The above are some examples of using the rotating member 600 as a detection electrode in the embodiments of the present invention. It should be understood that when the rotating member 600 is not reused as a detection electrode, it can also be installed through the above structure. The embodiments of the present invention do not limit this.

[0124] Please continue to refer to Figure 11 , Figure 11 is Figure 2 a partial enlarged view of another structure at 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 the fitting state signal between the light-emitting surface 123 and the skin to be treated.

[0125] 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 the fitting state signal of the skin care device and the skin to be treated.

[0126] In some embodiments, the fitting detection component 800 can be electrically connected to the 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.

[0127] 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.

[0128] Then, when the fitting detection component 800 includes a detection electrode, the detection electrode can directly contact the skin care device, thereby collecting the fitting state signal of the skin care device and the skin to be treated, for the fitting detection circuit to determine whether the light-emitting surface 123 is in contact with the skin to be treated.

[0129] When the fitting detection component 800 includes a proximity light sensor or a distance sensor, the optoelectronic signals collected by the proximity light sensor and the distance sensor can be used as the above-mentioned fitting state signal for the fitting detection circuit to determine whether the skin care device is in contact with the skin to be treated.

[0130] 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 for the fitting detection circuit to determine whether the skin care device is in contact with the skin to be treated.

[0131] 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 for the fitting detection circuit to determine whether the skin care device is in contact with the skin to be treated.

[0132] 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.

[0133] 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.

[0134] Therefore, compared with the fitting detection component 800 being located on the side of the rotating member 600 away from the light-emitting area 121, or the rotating member 600 being located on the side of the fitting detection component 800 away from the light-emitting area 121, in the embodiment of the present invention, 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.

[0135] 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 of the light-emitting area 121 in the width direction to reduce the friction between the skin care device and the skin to be treated.

[0136] 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.

[0137] 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.

[0138] Exemplarily, the prompting component can be electrically connected to the fitting detection circuit and is used to indicate the fitting state of 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.

[0139] Please continue to refer to Figure 12 , Figure 12 which is a schematic structural diagram of the rotation detection component provided by the embodiment of the present invention. 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.

[0140] In some embodiments, the skin care device may further include a controller, and the controller is electrically connected to the rotation detection component 900 and the light-emitting assembly 200 respectively. The controller is configured to: control the working state of the light-emitting assembly 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.

[0141] Exemplarily, the controller is configured to: determine the target light emitting frequency of the light emitting assembly 200 based on the rotation speed of the rotating member 600; and set the current light emitting frequency of the light emitting assembly 200 as the target light emitting frequency. Thus, the skin care device can emit light at a more appropriate frequency during movement to improve the skin care effect.

[0142] In some embodiments, the controller is configured to control the light emitting assembly 200 to emit light for a preset number of times whenever the rotating member 600 rotates a preset angle, thereby preventing the light emitting assembly 200 from emitting too much light to the same area of ​​the skin to be treated.

[0143] As mentioned above, in some embodiments, the skin care device may further include a prompt component, such as an indicator light, a display screen, a voice module, etc. The controller may also be electrically connected to the prompt component. The controller is configured to: when the rotation speed of the rotating member 600 is greater than a preset value, control the prompt component to remind the user. Thus, it can be avoided that the skin care device moves too fast, resulting in the light output component 200 failing to care for the skin to be treated.

[0144] In some implementations, the rotation detection component 900 may further include at least one of a photoelectric sensor, an encoder, and a Hall sensor, which is not limited in the embodiment of the present utility model.

[0145] For example, when the rotation detection component 900 includes a photoelectric sensor, the rotating member 600 may be provided with a triggering part that cooperates with the photoelectric sensor, and the photoelectric sensor is arranged on the rotation path of the triggering part, so that every time the rotating member 600 rotates a certain angle, the triggering part can trigger the photoelectric sensor to detect the rotation angle and / or rotation speed of the rotating member 600.

[0146] When the rotation detection component 900 includes an encoder, the roller of the encoder may be in contact with 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 .

[0147] Please continue to refer to Figure 13 , Figure 13 for Figure 12 Exploded 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.

[0148] 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.

[0149] In some embodiments, the number of the magnetic members 911 is plural, and the plural magnetic members 911 are evenly spaced along the circumferential direction of the driven wheel 91. Thus, through the cooperation of the Hall sensor and the plural magnetic members 911, the detection of the plural rotation angles of the plural rotating members 600 can be realized.

[0150] As mentioned above, the skin care device may further include a bracket assembly 34, and the bracket assembly 34 is disposed in the housing 100 and is installed with at least one of the cold compress assembly 400 and the light emitting assembly 200. Wherein, the rotation detection component 900 further includes a second mounting plate 346, and the second mounting plate 346 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, certain protection can be provided for the driven wheel 91 to prevent other components from interfering with the rotation of the driven wheel 91.

[0151] In some embodiments, one end of the rotating member 600 is rotatably mounted on the second mounting plate 346, so that the mounting of the rotating member 600 is more stable.

[0152] 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 form tolerance between the driven wheel 91 and the rotating member 600.

[0153] 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 in transmission connection with the rotating member 600 and the driven wheel 91, so that the transmission wheel 95 can follow the rotation of 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 to facilitate the reasonable distribution of the internal components of the housing 100.

[0154] Of course, the driven wheel 91 can 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 embodiments of the present invention do not limit this.

[0155] In some embodiments, one surface of the driven wheel 91 in the thickness direction faces the cold compress assembly 400.

[0156] It can be understood 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 member 41 and a refrigerating sheet 42. Among them, for the refrigerating effect of the refrigerating sheet 42, the light guide member 41 needs to be made larger to increase the contact area between the light guide member 41 and the refrigerating sheet 42. Based on this, in the embodiments of the present invention, one surface of the driven wheel 91 in the thickness direction faces the cold compress assembly 400, so that the relatively large space on the outer periphery of the cold compress assembly 400 can be fully utilized, which is convenient for the miniaturized design of the skin care device.

[0157] In addition, since the cold compress assembly 400 is disposed in the light emitting area 121 and the rotating member 600 is also located beside the light emitting area 121, setting the driven wheel 91 facing the cold compress assembly 400 can make the distance between the driven wheel 91 and the rotating member 600 closer, thereby avoiding the transmission chain between the driven wheel 91 and the rotating member 600 from being too long, and further improving the accuracy of the detection result of the rotation detection component 900.

[0158] 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 coincides with the orthographic projection of the cold compress assembly 400, so that the relatively large space on the outer periphery of the cold compress assembly 400 can be fully utilized, which is convenient for the miniaturized design of the skin care device.

[0159] 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 area of the orthographic projection of the driven wheel 91 coincides with the orthographic projection of the cold compress assembly 400.

[0160] As Figure 2 shown, in some embodiments, the skin care device may further include a filter assembly 1000. The filter assembly 1000 is disposed in the housing 100, and the filter assembly 1000 is located on the side of the light emitting assembly 200 facing the light emitting area 121 for filtering the light emitted by the light emitting assembly 200 towards the light emitting area 121.

[0161] In some embodiments, the light filtering component 1000 can be used to filter light with a wavelength less than or equal to 560 nanometers. It can be understood that when the skin care device performs treatments such as photon rejuvenation and hair removal on the skin to be treated, the light wavelengths required are usually between 460 nanometers and 1200 nanometers, and most of the light wavelengths generated by the light emitting component 200 are below 1200 nanometers. Therefore, the light filtering component 1000 can filter out the required light for hair removal and photon rejuvenation.

[0162] In some embodiments, the light filtering component 1000 can include at least two filter films, so that the light filtering effect can be improved through the at least two filter films.

[0163] In some embodiments, the skin care device further includes a driving component. The driving component is installed in the housing 100, and the driving component is in transmission connection with the rotating member 600 for driving the rotating member 600 to rotate.

[0164] Therefore, during use, the driving component can be used to drive the rotating member 600 to rotate to control the movement of the skin care device on the skin to be treated.

[0165] It can also be understood that the skin care device can 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.

[0166] 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 can 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.

[0167] 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 can 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 invention do not limit this.

[0168] 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, and the working information of the light emitting component 200 can include at least one of the light emitting frequency, light emitting intensity, and light emitting mode of the light emitting component 200, and the movement information parameters can include at least one of movement speed, movement distance, and movement direction; control the working state of the driving component based on the movement information parameters.

[0169] 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. The embodiments of the present invention are not limited thereto.

[0170] The embodiments of the present invention have been described in detail above. Specific examples are used herein to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
