In view of this, in the embodiments of the present invention, "plurality" can also be understood as "at least two". "At least one" can be understood as one or more, for example, one, two or more. For example, including at least one means including one, two or more, and there is no limit on which ones are included. For example, including at least one of A, B and C, then A, B, C, A and B, A and C, B and C, or A, B and C can be included.

[0029] The embodiment of the utility model provides a skin care device, which may be a hair removal device or a skin rejuvenation device, etc. Of course, the skin care device may also be any other device for treating the skin, which is not limited by the embodiment of the utility model.

[0030] Please refer to Figure 1 , Figure 1 The skin care device of the embodiment of the utility model comprises a housing 100 and a light emitting component 200, wherein the light emitting component 200 is arranged in the housing 100 and is used to generate light to be emitted to the skin to be treated.

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

[0032] Of course, the skin care device may also include a cold compress component 400. The cold compress component 400 is disposed on the housing 100 and is used to apply cold compress to the skin to be treated, so as to reduce or even eliminate the pain or heat sensation generated during hair removal or skin rejuvenation. Accordingly, the heat dissipation component 300 may be used only to dissipate heat from the light emitting component 200, and 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 embodiment of the utility model. The following is an example description in combination with the light output structure of the skin care device.

[0034] The housing 100 is provided with a light emitting area 121. The light emitting assembly 200 faces the light emitting area 121 to generate light emitted from the light emitting area 121 to the skin to be treated. The cold compress assembly 400 can be arranged at the light emitting area 121 to apply cold compress to the skin to be treated.

[0035] It can be understood that skin care devices can be divided into different types according to the different types of light generated by the light output component 200. For example, the light output component 200 can be used to generate laser, which is a laser light source 21 component, and the skin care device is a laser skin care device; for another example, the light output 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 skin care device; for another example, the light output component 200 can be an LED light source 21 component.

[0036] The utility model is mainly explained below by taking the light emitting component 200 as an IPL light source component as an example. The light emitting principle of this type of skin care equipment is: a capacitor is connected to a power supply, and a transformer component is used to step up the voltage to charge the capacitor. When the capacitor is charged to a preset value and the controller receives a trigger signal, the electric energy in the capacitor is released, and the instantaneous voltage can reach several hundred volts, thereby stimulating the lamp to instantly release a strong pulse of light, thereby completing a light emission.

[0037] Next, the technical solution of the embodiment of the utility model will be described with examples in combination with the cold compress assembly 400.

[0038] 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.

[0039] The cold compress component 400 is disposed at the light emitting area 121. The cold compress component 400 may be installed in the light emitting area 121, or may be disposed on the surrounding side of the light emitting area 121, or the cold compress component 400 may be partially disposed in the light emitting area 121 and partially disposed on the surrounding side of the light emitting area 121. The embodiment of the utility model does not limit this. It should be noted that when the cold compress component 400 is installed in the light emitting area 121, the cold compress component 400 directly applies cold compress to the skin to be treated; when the cold compress component 400 is disposed on the surrounding side of the light emitting area 121, the cold compress component 400 first applies cold compress to the skin surrounding the skin to be treated, so as to transfer cold energy to the skin to be treated through the skin surrounding the skin, so as to achieve indirect cold compress to the skin to be treated.

[0040] For example, the cold compress assembly 400 may include a light guide component 41 and a cooling sheet 42. The light exit area 121 is an opening structure such as a light exit port and a light exit hole, and the light guide component 41 is arranged in the light exit area 121 to transmit the light emitted by the light exit assembly 200. The cooling sheet 42 is thermally connected to the light guide component 41. For example, the cooling sheet 42 is directly attached to the light guide component 41 or attached to the light guide component 41 through a heat conductive medium such as thermal conductive silicone grease.

[0041] Furthermore, the light guide component 41 can be cooled by the cooling sheet 42. The cooled light guide component 41 is exposed from the light exit area 121 so as to come into contact with the skin. The light guide component 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 cooling sheet 42 to provide a cold compress for the user.

[0042] Specifically, the cooling plate 42 is also called a semiconductor cooling plate, which utilizes the Peltier effect of semiconductor materials. When direct current passes through a couple formed by two different semiconductor materials connected in series, heat can be absorbed and released at both ends of the couple, thereby achieving the purpose of cooling.

[0043] The light-guiding component 41 may be made of sapphire or other light-guiding materials, which is not limited in the embodiment of the present invention.

[0044] In an optional embodiment, the cold compress assembly 400 may further include a cold compress (not shown in the figure) and a cooling sheet 42. The light exit area 121 is an opening structure such as a light exit port and a light exit hole, and the cold compress is arranged on the open end surface of the light exit area 121. The cooling sheet 42 is thermally connected to the cold compress; for example, the cooling sheet 42 is directly attached to the cold compress or attached to the cold compress through a heat conductive medium such as thermal conductive silicone grease.

[0045] Furthermore, the cold compress can be cooled by the cooling sheet 42, and the cooled cold compress is exposed from the light emitting area 121 so as to come into contact with the skin to provide a cold compress for the user.

[0046] For example, the cold compress may be a ring-shaped metal part arranged around the light emitting area 121 .

[0047] In another optional embodiment, the cold compress assembly 400 includes a cold compress member (not shown in the figure) having a flow cavity, a refrigerant medium (such as a refrigerant liquid or a refrigerant gas) that can flow in the flow cavity, and a driving device (such as a compressor, etc.) for driving the refrigerant medium to circulate, so that the cooling medium can be used to achieve the cold compress function of the cold compress member. The light emitting area 121 is an open structure such as a light emitting port and a light emitting hole, and the cold compress member is arranged in a circumferential shape on the open end surface of the light emitting area 121.

[0048] In some embodiments, the heat dissipation assembly 300 may include a fan, which is disposed in the housing 100 and is used to drive air convection inside and outside the housing 100 , thereby dissipating heat for the cold compress assembly 400 and / or the light output assembly 200 .

[0049] The light exit area 121 may be formed on an end surface of one end of the housing 100 in the length direction, or may be formed on a peripheral side surface of one end of the housing 100 in the length direction, which is not limited in the embodiment of the present utility model.

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

[0051] The following is an explanation of the other structures of the skin care device with examples.

[0052] Please continue to refer to Figure 2 , Figure 2 for Figure 1The schematic diagram of the structure of the rotating member of the skin care device is 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. The skin care device may further include a rotating member 600, which 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 taking care of multiple areas to be treated on the arm, the user can first place the rotating member 600 against the user's arm, and then drive the housing 100 or the skin care device to move between the multiple areas to be treated by rolling the rotating member 600 on the skin, so that the light-emitting component 200 completes the care of the multiple areas to be treated. In this process, the friction between the skin care device and the skin can be reduced by rolling the rotating member 600 on the skin, thereby avoiding the inconvenience of moving the skin care device, or excessive friction on the skin causing skin abrasions, discomfort, etc. In addition, compared to the user lifting the skin care device from one area to be treated and placing it on another area to be treated, the rotating member 600 makes the skin care device have the advantages of easy movement and a short moving path, thereby improving the efficiency of skin care.

[0054] The rotating member 600 may include at least one of a ball, a roller and a roller, which is not limited in the embodiment of the present utility model.

[0055] Please continue to refer to Figure 3 , Figure 3 for Figure 2 Schematic diagram of the matching structure of the rotating member and the housing. Exemplarily, 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 so as 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 may be rotatably mounted on the shell 100 by the mounting shaft 62 directly contacting the shell 100 to form a rotatable connection, or the mounting shaft 62 may be rotatably mounted on some parts fixed to the shell 100 to be indirectly rotatably mounted on the shell 100, and the embodiment of the utility model is not limited to this.

[0057] The rotating member body 61 may be cylindrical or spherical. When the rotating member body 61 is cylindrical, the mounting shaft 62 may be connected to the end of the rotating member body 61 , which is not limited in the embodiment of the present utility model.

[0058] Taking the rotating member body 61 as a columnar shape, 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, and the two mounting shafts 62 are coaxially arranged and located on opposite sides of the rolling member body. Thus, the installation 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 may be in a polygonal column shape, so that during the rotation of the mounting shaft 62 , the mounting shaft 62 may periodically radially jump 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.

[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 periodically radially jump 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 structural schematic diagram of the rotating member is 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 extend or retract following the rotation of the mounting shaft 62. For example, the elastic telescopic member 621 can be a ball screw, etc. Therefore, during the rotation of the mounting shaft 62, the mounting shaft 62 can periodically radially jump 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.

[0062] Please continue to refer to Figure 5 and Figure 6 , Figure 5 for Figure 3 Exploded diagram of Figure 6 for Figure 2 In some embodiments, a light exit hole is provided on one side surface of the housing 100 to form a light exit area 121. The housing 100 is provided with a mounting hole 122, the mounting hole 122 is at least partially located on the light exit surface 123, the mounting hole 122 is arranged adjacent to the light exit area 121, and the rotating member body 61 is passed through the mounting hole 122 to partially protrude from the light exit surface 123.

[0063] It can be understood that by arranging the mounting hole 122 and the light emitting area 121 adjacent to each other, the distance between the rotating member body 61 and the light emitting area 121 can be made closer, thereby avoiding the need to set a larger area for the light emitting surface 123 of the shell 100 to arrange the mounting holes 122 and the light emitting area 121 with larger spacing, so that the user can more conveniently and accurately fit the light emitting area 121 to the skin to be treated during use.

[0064] In some embodiments, the inner wall of the shell 100 is further provided with a mounting groove 124, and the mounting groove 124 is connected to the mounting hole 122, and the mounting shaft 62 is rotatably disposed in the mounting groove 124, so that by hiding the connection between the rotating member 600 and the shell 100 inside the shell 100, it can be avoided that the connection between the rotating member body 61 and the shell 100 is exposed and accidentally damaged, thereby improving 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 partially protrudes from the light emitting surface 123 and partially protrudes from the side surface 125. For example, 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 partially protrudes from the light emitting surface 123 and partially protrudes from the side surface 125.

[0066] It is understandable 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 a pit, and the light-emitting surface 123 and part of the side surface 125 will be accommodated in the pit. At this time, since the rotating member body 61 partially protrudes from the light-emitting surface 123, the friction between the light-emitting surface 123 and the skin to be treated can be reduced, and the rotating member body 61 also partially protrudes 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 can roll more smoothly on the skin to be treated, thereby improving the user experience.

[0067] In some embodiments, the height of the rotating member 600 (for example, the rotating member body 61 of the rotating member 600) protruding from the outer surface of the shell 100 is less than or equal to 1.2 mm, thereby preventing the rotating member body 61 from protruding too much from the outer surface of the shell 100, resulting in the light-emitting surface 123 being unable to fit with the skin to be treated, 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.

[0068] Exemplarily, the height of the rotating member body 61 protruding from the outer surface of the shell 100 can be 0.21 mm, 0.23 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.411 mm, 0.467 mm, 0.5 mm, 0.57 mm, 0.6 mm, 0.605 mm, 0.631 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.897 mm, 0.9 mm, 0.95 mm, 1 mm, 1.5 mm or 1.2 mm, which is not limited to the embodiments of the present invention.

[0069] In some embodiments, there are at least two rotating members 600. The rotating members 600 are extended along the length direction of the light emitting area 121, and a rotating member 600 is disposed on each side of the light emitting area 121 along the width direction.

[0070] Thus, by at least two rotating members 600 contacting the skin to be treated, the friction between the skin care device and the skin can be effectively reduced. At the same time, since a rotating member 600 is 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 of the skin care device during movement can be more uniform, 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, thereby ensuring that the rotating member 600 has a sufficiently large 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 portion of the rotating member 600 protruding from the outside of the housing 100 (such as the rotating member body 61) gradually decreases from the middle to the two ends. It is understandable 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 pit. At this time, the structure of the rotating member body 61 that is thick in the middle and thin at both ends can well match the arc-shaped pit to improve the user experience.

[0073] In some embodiments, the rotating member 600 is further configured to be telescopically inserted into the housing 100, so that the height of the rotating member 600 protruding from the light emitting surface 123 is adjustable. It is understandable 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 user's skin concavity 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 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 71 is a schematic diagram of the first structure of the first elastic component of the embodiment of the utility model. In some embodiments, the skin care device may include a first elastic component 71. The first elastic component 71 is disposed in the housing 100 and is used 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 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 compressed and arranged on the side of the rotating member 600 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 installed 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 undergoes elastic recovery to drive the rotating member 600 to extend and reset.

[0076] It can also be understood that, since the rotating member 600 is in contact with the first arc surface 1241 , during the extension and retraction process of the rotating member 600 , the first arc surface 1241 can have a good limiting effect on the rotating member 600 .

[0077] In some embodiments, the radius of curvature of the first curved surface 1241 may be equal to the radius of the mounting shaft 62. Optionally, the radius of curvature of the first curved surface 1241 may also be greater than the radius of the mounting shaft 62, which is not limited in the embodiment of the utility model. When the radius of curvature of the first curved surface 1241 is greater than the radius of the mounting shaft 62, the mounting shaft 62 may abut against different positions of the first curved surface 1241, thereby adjusting the height of the rotating member body 61 protruding from the light emitting surface 123 and the side surface 125 at the same time.

[0078] As mentioned above, in some embodiments, the shell 100 may be provided with a mounting hole 122 and a mounting groove 124, the rotating member body 61 is passed through the mounting hole 122 so as to partially protrude from the outside of the light emitting area 121, the mounting groove 124 is connected to the mounting hole 122, and the mounting shaft 62 is rotatably installed in the mounting groove 124, so that the groove wall of the mounting groove 124 can form a 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 Fig. 9 , Figure 8 This is a schematic diagram of an installation structure of a rotating member of an embodiment of the utility model. Fig. 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 component 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, 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 the other torsion arm of the torsion spring is pressed against the rotating member 600 (for example, the mounting shaft 62 of the rotating member 600), so that the rotating member 600 can be pushed in the direction of extending out of the housing 100 by the torsion spring.

[0089] In some embodiments, the rotating member 600 is detachably mounted on the housing 100 , so that the user can conveniently disassemble the rotating member 600 for maintenance such as cleaning and replacement.

[0090] Please continue to refer to Fig.10 , Fig.10 for Figure 7 Another perspective structural schematic diagram of the first elastic component is shown. Exemplarily, the housing 100 is also provided with a mounting hole 122 at least partially located on the light emitting surface 123. The skin care device also includes a second elastic component 72. The second elastic component 72 is at least partially disposed at the mounting hole 122. The rotating member 600 is rotatably disposed in the mounting hole 122 so that the rotating member 600 partially protrudes from the light emitting surface 123, so that it can 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 component 72, so that the rotating member 600 can compress the second elastic component 72 and move axially to a disassembled state. When the rotating member 600 moves to the disassembled state, the rotating member 600 can be detached 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 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.

[0092] 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.

[0093] 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:

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] In some embodiments, the second elastic component 72 includes a second elastic member 721 and a second floating member 722 . The second floating member 722 is disposed on a side of the second elastic member 721 close to the rotating member 600 and abuts against an end surface 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, the inner surface of the housing 100 is provided with a vertical plate 126, which is arranged 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 compressed between the vertical plate 126 and the second floating member 722.

[0101] In some embodiments, the skin care device includes a first elastic component 71, and the first elastic component 71 is used to push the peripheral surface of the mounting shaft 62 to press against the inner surface of the housing 100 to form a rotational fit. Thus, the first elastic component 71 can drive the rotating member 600 to move in a direction extending outward from the light emitting area 121. Then, continuing to take the example that each end of the rotating member body 61 along the left and right directions is provided with a mounting shaft 62, and the opening of the mounting hole 122 is arranged upward, one of the disassembly processes of the rotating member 600 can be as follows:

[0102] First, the rotating member body 61 is pushed to the right so that the mounting shaft 62 at the left end of the rotating member body 61 moves to leak out of the mounting hole 122, and the second elastic component 72 at the right end of the rotating member body 61 is compressed. Then, the mounting shaft 62 at the left end of the rotating member body 61 is moved 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, and the mounting shaft 62 at the right end of the rotating member body 61 moves downward accordingly, and the first elastic component 71 at the right end of the rotating member body 61 is compressed, so that the rotating member 600 is tilted in a posture with the left end facing up and the right end facing down; finally, the rotating member body 61 is taken out tilted in the upper left direction so that the mounting shaft 62 at the right end of the rotating member body 61 is also separated from the housing 100, thereby completing the disassembly of the rotating member 600, and vice versa, the installation of the rotating member 600 can be completed.

[0103] In some embodiments, one end of the first elastic component 71 close to the mounting shaft 62 is located on the side of the second floating component 722 close to the mounting shaft 62. Thus, during use, the first elastic component 71 can be prevented from interfering with the second elastic component 72 when elastic recovery occurs after being compressed, thereby preventing the rotating component 600 from being pressed tightly.

[0104] Exemplarily, as mentioned above, the first elastic component 71 includes a first elastic component 711 and a first floating component 712, wherein the first floating component 712 is disposed on a side of the first elastic component 711 close to the rotating component 600 and abuts against the peripheral surface of the rotating component 600. The second elastic component 72 includes a second elastic component 721 and a second floating component 722, wherein the second floating component 722 is disposed on a side of the second elastic component 721 close to the rotating component 600 and abuts against the end surface of the mounting shaft 62. At this time, along the axial direction of the rotating component body 61, the orthographic projection of the first floating component 712 and at least part of the orthographic projection of the first elastic component 711 are both located within the orthographic projection of the second floating component 722.

[0105] In some embodiments, the skin care device further includes a fitting detection module, which 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, which may be any fitting detection circuit in the prior art, and the embodiment of the utility model is not limited thereto.

[0106] It is understandable that, since the rotating member 600 partially protrudes from the light emitting surface 123, after the rotating member 600 abuts against the skin to be treated, there is a gap between the light emitting surface 123 and the skin to be treated, which not only easily causes light leakage through the gap between the light emitting surface 123 and the skin to be treated, but also easily reduces the care effect of the skin care device. Based on this, in the embodiment of the utility model, when the fit detection module detects that the skin care device and the skin to be treated are not fit, the skin care device can perform corresponding processing actions, such as controlling the light emitting component 200 to stop emitting light, prompting the user that it is not fit, etc., and the embodiment of the utility model does not limit this.

[0107] In some embodiments, the fitting detection module can be electrically connected to the rotating member 600 to detect the fitting state of 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 set on the light emitting surface 123, so that the area of ​​the light emitting surface 123 can be reduced, so that the user can 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 made entirely of metal or any other conductive material. Therefore, even if the surface of the rotating member 600 is worn to a certain extent, the stability and reliability of the electrical connection of the rotating member 600 will not be affected.

[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 can be formed on the rotating member 600 by spraying, evaporation, electroplating, etc., and the embodiment of the utility model does not limit this. Then in the actual preparation process, only the conductive layer can be made of conductive material, and the rotating member body 61 can be made of any material with low cost, easy manufacturing, wear resistance, etc. according to actual needs.

[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 provided on the rotating member 600 by means of clamping, screwing, welding, etc., and the embodiment of the utility model does not limit this. Then, in the actual preparation process, only the conductive sheet can be made of conductive material, and the rotating member body 61 can be made of any material with low cost, easy manufacturing, wear resistance, etc. according to actual needs.

[0114] In some embodiments, the skin care device further includes a first elastic component 71, and the first elastic component 71 is made of a conductive material. The first elastic component 71 is electrically connected to the fitting detection module, and the first elastic component 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 component 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 component 71 are worn to a certain extent, the first elastic component 71 can be driven by its own elastic force to abut against the rotating member 600, thereby ensuring the reliability and stability of the electrical connection.

[0115] In some embodiments, the number of the first elastic components 71 and the number of the rotating components 600 are at least two, and different rotating components 600 are electrically connected to the fitting detection module through different first elastic components 71, so that multiple detection electrodes can be formed through multiple rotating components 600 to improve the accuracy and reliability of detection.

[0116] For example, Figure 8 As shown, as mentioned above, 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.

[0117] For example, the bracket assembly 34 is provided with a mounting post 3431 . The first elastic component 71 may include a torsion spring, which 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 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.

[0119] 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 utility model is not limited to 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 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.

[0121] 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.

[0122] 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.

[0123] The above are some examples of the rotating member 600 being reused as a detection electrode in the embodiment of the utility model. 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 utility model does not limit this.

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

[0125] In some embodiments, the fit 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 to roll on the skin to be treated. At the same time, the fit detection component 800 can cooperate with the skin to be treated to collect the fit state signal of the skin care device and the skin to be treated.

[0126] In some embodiments, the fit detection component 800 may be electrically connected to a fit detection circuit that is used to obtain the fit state between the light emitting surface 123 and the skin to be treated based on the fit state signal.

[0127] Exemplarily, the fit 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 fit detection component 800 includes a detection electrode, the detection electrode can directly contact the skin care device, thereby collecting the fit status signal between the skin care device and the skin to be treated, so that the fit detection circuit can determine whether the light surface 123 fits the skin to be treated.

[0129] When the fit detection component 800 includes a proximity light sensor or a distance sensor, the photoelectric signal collected by the proximity light sensor or the distance sensor can be used as the above-mentioned fit status signal for the fit detection circuit to determine whether the skin care device fits the skin to be treated.

[0130] When the fit detection component 800 includes a temperature sensor, the body temperature signal detected by the temperature sensor can be used as the above-mentioned fit status signal for the fit detection circuit to determine whether the skin care device fits the skin to be treated.

[0131] When the fit detection component 800 includes a pressure sensor, the pressure-temperature signal detected by the pressure sensor can be used as the above-mentioned fit state signal for the fit detection circuit to determine whether the skin care device fits the skin to be treated.

[0132] In some embodiments, the number of the fit detection components 800 is at least two, so that the accuracy and reliability of detection can be improved by using multiple fit detection components 800.

[0133] Exemplarily, the number of the rotating members 600 and the number of the fitting detection components 800 are both at least two, and the rotating members 600 and the fitting detection components 800 are alternately arranged around the circumference of the light emitting area 121 .

[0134] Therefore, compared to 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 utility model, 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, so that the user can fit the light emitting surface 123 more accurately onto the skin to be treated.

[0135] In some embodiments, the number of the rotating members 600 is at least two, and a rotating member 600 is provided on each side of the light exit area 121 in the width direction. Thus, longer rotating members 600 can be provided on both sides of the light exit 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, each side of the light emitting area 121 along the length direction is provided with a fitting detection component 800. Thus, a larger space can be reserved on both sides of the light emitting area 121 along the width direction to set a longer rotating member 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 prompt component, such as an indicator light, a display screen, a voice module, etc.

[0138] Exemplarily, the prompt component can be electrically connected to the fitting detection circuit and used to indicate the fitting state of the skin care device and the skin to be treated. The prompt component includes at least one of an indicator light and a voice module, so as to remind the user to fit the light emitting surface 123 of the skin care device to the skin to be treated in time to improve the care effect.

[0139] Please continue to refer to Fig.12 , Fig.12 A schematic diagram of the structure of the rotation detection component provided in an embodiment of the utility model. 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, the movement speed, distance and other information 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, which is electrically connected to the rotation detection component 900 and the light output component 200. The controller is configured to control the working state of the light output 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.

[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 Fig.13 , Fig.13 for Fig.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, 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.

[0150] 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.

[0151] 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.

[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 shape and position 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 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.

[0154] 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 utility model does not limit this.

[0155] In some embodiments, one side surface of the driven wheel 91 in the thickness direction is disposed opposite to the cold compress assembly 400 .

[0156] 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 utility model, 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 miniaturization design of the skin care device.

[0157] 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.

[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 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.

[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] like Figure 2 As 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 is located on a side of the light emitting assembly 200 facing the light emitting area 121 to filter the light emitted from the light emitting assembly 200 to the light emitting area 121.

[0161] In some embodiments, the filter assembly 1000 can be used to filter light with a wavelength less than or equal to 560 nanometers. It is understandable that the wavelength of light required by the skin care device for photorejuvenation and hair removal of the treated skin is usually between 460 nanometers and 1200 nanometers, and the wavelength of most of the light generated by the light output assembly 200 is below 1200 nanometers, so the filter assembly 1000 can filter out the required light for hair removal and photorejuvenation.

[0162] In some embodiments, the filter assembly 1000 may include at least two filters, so that the filtering effect can be improved by the at least two filters.

[0163] In some embodiments, the skin care device further comprises a driving assembly which is installed in the housing 100 and is in transmission connection with the rotating member 600 to drive the rotating member 600 to rotate.

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

[0165] It is also understandable that the skin care device may further include a controller, which is electrically connected to the driving component and the light emitting component 200. 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 movement information parameters of the skin care device on the skin to be treated based on the working information of the driving component, the movement information parameters may include at least one of the moving speed, moving distance and moving direction; and control the working state of the light output 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 moving speed of the skin care device, and the embodiment of the utility model is not limited to 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, 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, and the movement information parameters may include at least one of the moving speed, moving distance and moving direction; and control the working state of the driving component based on the movement information parameters.

[0169] In some embodiments, the driving assembly may include a motor. Of course, the driving assembly may also include any other power source that can drive the rotating member 600 to rotate, and the embodiment of the utility model is not limited to this.
