[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0028] In addition, in the embodiments of the present application, "plurality" refers to two or more. In view of this, in the embodiments of the present application, "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 does not limit which ones are included. For example, "including at least one of A, B, and C" means including A, B, C, A and B, A and C, B and C, or A, B, and C.

[0030] An embodiment of the present application 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 used to treat the skin, and the embodiment of the present application does not limit this.

[0031] Please refer to Figure 1 , Figure 1 Schematic diagram of the structure of the skin care device according to an embodiment of the present application. The skin care device comprises 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 directed toward the skin to be treated.

[0032] 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 from the light emitting component 200 .

[0033] Of course, the skin care device may also include a cold compress assembly 400. The cold compress assembly 400 is disposed within the housing 100 and is used to apply a cold compress to the skin being treated, thereby reducing or even eliminating the pain or heat sensation experienced during hair removal or skin rejuvenation. Accordingly, the heat dissipation assembly 300 may be used solely to dissipate heat from the light output assembly 200. Alternatively, the heat dissipation assembly 300 may be used to dissipate heat from both the light output assembly 200 and the cold compress assembly 400, thereby enhancing the cold compress effect of the cold compress assembly 400.

[0034] The above is an overall description of the skin care device in the embodiment of the present application. The following is an example description in combination with the light output structure of the skin care device.

[0035] 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 that is emitted from the light emitting area 121 toward the skin to be treated. The cold compress assembly 400 can be disposed at the light emitting area 121 to apply a cold compress to the skin to be treated.

[0036] 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-emitting component 200. 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 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 skin care device; for another example, the light-emitting component 200 can be an LED light source 21 component.

[0037] In this application, the following mainly uses the light-emitting component 200 as an IPL light source component as an example for explanation. The light-emitting principle of this type of skin care equipment is: the capacitor is connected to the power supply, and the transformer component boosts 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 hundreds of volts, thereby stimulating the lamp tube to instantly release strong pulsed light, thereby completing one light emission.

[0038] Next, the technical solution of the embodiment of the present application will be described with examples in conjunction with the cold compress assembly 400.

[0039] It should be noted that the light exit area 121 can be an opening structure such as a light exit port or light exit hole provided on the housing 100. Optionally, the light exit area 121 can also be formed by some light-transmitting areas on the housing 100, which is not limited in the present embodiment.

[0040] The cold compress assembly 400 is disposed at the light emitting area 121. The cold compress assembly 400 may be installed in the light emitting area 121, or the cold compress assembly 400 may be disposed around the light emitting area 121, or the cold compress assembly 400 may be partially disposed in the light emitting area 121 and partially disposed around the light emitting area 121. This embodiment of the present application does not limit this. It should be noted that when the cold compress assembly 400 is installed in the light emitting area 121, the cold compress assembly 400 directly applies a cold compress to the skin to be treated; when the cold compress assembly 400 is disposed around the light emitting area 121, the cold compress assembly 400 first applies a cold compress to the skin around the skin to be treated, so as to transfer the cold energy to the skin to be treated through the skin around the skin, thereby achieving an indirect cold compress to the skin to be treated.

[0041] For example, the cold compress assembly 400 may include a light guide component 41 and a cooling plate 42. The light exit region 121 may be an opening structure such as a light exit port or light exit hole. The light guide component 41 is disposed in the light exit region 121 to transmit light emitted by the light exit assembly 200. The cooling plate 42 is thermally connected to the light guide component 41. For example, the cooling plate 42 may be directly attached to the light guide component 41 or attached to the light guide component 41 via a thermally conductive medium such as thermal grease.

[0042] 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 that it can come into contact with the skin. In this way, 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.

[0043] Specifically, the cooling plate 42 is also called a semiconductor cooling plate. It uses the Peltier effect of semiconductor materials. When direct current passes through a galvanic couple composed of two different semiconductor materials connected in series, heat can be absorbed and released at both ends of the galvanic couple respectively, thereby achieving the purpose of cooling.

[0044] 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 application.

[0045] In an optional embodiment, the cold compress assembly 400 may further include a cold compress (not shown) and a cooling plate 42. The light exit area 121 is an open structure such as a light exit port or light exit hole, and the cold compress is disposed on the open end surface of the light exit area 121. The cooling plate 42 is thermally connected to the cold compress; for example, the cooling plate 42 is directly attached to the cold compress or attached to the cold compress via a thermally conductive medium such as thermal grease.

[0046] 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, thereby providing a cold compress to the user.

[0047] For example, the cold compress may be a ring-shaped metal member disposed around the light exit area 121 .

[0048] In another optional embodiment, the cold compress assembly 400 includes a cold compress having a flow cavity (not shown in the figure), a refrigerant (such as a refrigerant liquid or refrigerant gas) that can flow within the flow cavity, and a drive device (such as a compressor, etc.) for driving the refrigerant to circulate. In this way, the cooling medium can be used to achieve the cold compress function of the cold compress. The light emitting area 121 is an open structure such as a light outlet or a light outlet hole, and the cold compress is arranged in a circumferential shape on the open end surface of the light emitting area 121.

[0049] 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 .

[0050] The light exit area 121 may be formed on an end surface at one end of the housing 100 in the longitudinal direction, or may be formed on a peripheral side surface at one end of the housing 100 in the longitudinal direction, which is not limited in the embodiment of the present application.

[0051] For example, the housing 100 includes a main housing 11 and a head housing 12. The main housing 11 is in an elongated shape, forming the main structure of the housing 100. The head housing 12 is disposed around the main housing 11 and has a light emitting area 121 on the end surface of the head housing 12 facing away from the main housing 11.

[0052] The following continues to illustrate with examples in combination with other structures of the skin care device.

[0053] Please continue to refer to Figure 2 , Figure 2 for Figure 1 The skin care device is shown as a schematic diagram of a rotating member. The outer surface of the housing 100 includes a light-emitting surface 123, with the light-emitting region 121 located on the light-emitting surface 123. The skin care device may further include a rotating member 600 rotatably mounted on the housing 100. The rotating member 600 at least partially protrudes from the light-emitting surface 123, enabling the rotating member 600 to roll over the skin to be treated.

[0054] Then, taking the example of a user caring for multiple areas to be treated on their 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 can complete 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 then placing it on another area to be treated, the rotating member 600 makes the skin care device easier to move and has a shorter movement path, thereby improving skin care efficiency.

[0055] The rotating member 600 may include at least one of a ball, a roller, and a roller, which is not limited in this embodiment of the present application.

[0056] Please continue to refer to Figure 3 , Figure 3 for Figure 2 Schematic diagram of the mating structure of the rotating member and the housing. For example, 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, with a portion protruding from the light-emitting surface 123. The mounting shaft 62 is connected to the rotating member body 61 and is rotatably mounted on the housing 100.

[0057] It should be noted that the mounting shaft 62 can be rotatably mounted on the shell 100 by the mounting shaft 62 directly contacting the shell 100 to form a rotational connection, or the mounting shaft 62 can be rotatably mounted on some components fixed to the shell 100 to be indirectly rotatably mounted on the shell 100. The embodiments of the present application do not limit this.

[0058] The rotating member body 61 can be cylindrical or spherical. When the rotating member body 61 is cylindrical, the mounting shaft 62 can be connected to the end of the rotating member body 61. This embodiment of the present application does not limit this.

[0059] For example, if the rotating member body 61 is cylindrical, a mounting shaft 62 is provided at each end of the rotating member body 61. Alternatively, the rotating member body 61 may be a roller or ball bearing, with two mounting shafts 62 coaxially disposed on opposite sides of the rotating member body. This provides for more stable and reliable installation of the rotating member body 61.

[0060] In some embodiments, the mounting shaft 62 can be polygonal, 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] 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.

[0062] Please continue to refer to Figure 4 , Figure 4 for Figure 3 Another schematic diagram of the rotating member is shown. In some embodiments, the mounting shaft 62 is provided with an elastic member 621, which is configured to extend or retract as the mounting shaft 62 rotates. For example, the elastic member 621 can be a ball screw. As the mounting shaft 62 rotates, the mounting shaft 62 can periodically radially oscillate, providing vibration feedback as the rotating member 600 drives the skin care device to roll across the treated skin surface.

[0063] Please continue to refer to Figure 5 and Figure 6 , Figure 5 for Figure 3 Exploded diagram, Figure 6 for Figure 2 A partial enlarged view at X. In some embodiments, a light exit hole is provided on one side of the housing 100 to form a light exit area 121. A mounting hole 122 is provided through the housing 100. The mounting hole 122 is at least partially located on the light exit surface 123. The mounting hole 122 is disposed adjacent to the light exit area 121. The rotating member body 61 is disposed through the mounting hole 122 so as to partially protrude from the light exit surface 123.

[0064] 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 part 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 a larger spacing, and then the user can more conveniently and accurately fit the light emitting area 121 to the skin to be treated during use.

[0065] In some embodiments, the inner wall of the shell 100 is further provided with a mounting groove 124, which is connected to the mounting hole 122, and the mounting shaft 62 is rotatably set in the mounting groove 124. Therefore, by hiding the connection between the rotating part 600 and the shell 100 inside the shell 100, the connection between the rotating part body 61 and the shell 100 can be avoided from being exposed and accidentally damaged, thereby improving the stability and reliability of the installation of the rotating part 600.

[0066] 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.

[0067] It is understood that, since skin itself has a certain degree of elasticity, when the rotating member 600 and the light-emitting surface 123 come into contact with the skin to be treated, the skin to be treated is squeezed to form a depression, into which the light-emitting surface 123 and part of the side surface 125 are accommodated. 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 is reduced, and the rotating member body 61 also partially protrudes from the side surface 125, which reduces the friction between the side surface 125 and the skin to be treated. This makes the rotating member 600 roll more smoothly on the skin to be treated, thereby improving the user experience.

[0068] 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, causing the light-emitting surface 123 to be unable to fit with the skin to be treated, thereby ensuring the skin care effect and avoiding the gap between the light-emitting surface 123 and the skin to be treated and light leakage.

[0069] Illustratively, 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 application.

[0070] 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 region 121, and a rotating member 600 is provided on each side of the light emitting region 121 along the width direction.

[0071] Thus, by having at least two rotating members 600 in contact with the skin to be treated, the friction between the skin care device and the skin can be effectively reduced. Furthermore, since a rotating member 600 is provided on each side of the light emitting area 121 along the width direction, the force applied to each portion of the light emitting surface 123 of the skin care device during movement can be more evenly distributed, allowing the skin care device to move more stably and reliably.

[0072] 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.

[0073] In some embodiments, the diameter of the portion of the rotating member 600 protruding from the exterior of the housing 100 (e.g., the rotating member body 61) gradually decreases from the center toward the ends. As will be appreciated, since skin itself has a certain degree of elasticity, when the rotating member 600 and the light-emitting surface 123 contact the skin to be treated, the treated skin is squeezed, forming a curved recess. In this case, the structure of the rotating member body 61, which is thicker in the center and thinner at the ends, perfectly matches this curved recess, enhancing the user experience.

[0074] In some embodiments, the rotating member 600 is further configured to be retractably mounted within the housing 100, allowing for an adjustable height of the rotating member 600 protruding from the light-emitting surface 123. It is understood that the elasticity of different users' skin varies, and therefore, when a user places the skin care device on the skin to be treated, the degree and shape of the skin's indentation also varies. In this case, the height of the rotating member 600 protruding from the outside of the light-emitting area 121 can be adaptively adjusted to ensure that both the rotating member 600 and the light-emitting surface 123 conform to the skin, thereby ensuring a skin care effect while preventing light leakage caused by a gap between the light-emitting surface 123 and the skin to be treated.

[0075] Please continue to refer to Figure 7 , Figure 7This is a schematic diagram of a first structural embodiment of the first elastic component of the present application. 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 used to drive the rotating member 600 to move in a direction extending beyond 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 conforms to the skin.

[0076] Exemplarily, the inner surface of the housing 100 includes a first curved surface 1241 located inside the light-emitting surface 123, and the rotating member 600 abuts against the first curved surface 1241. The first elastic component 71 is compressed and arranged on the side of the rotating member 600 facing away from the first curved surface 1241 to drive the rotating member 600 to abut against the first curved surface 1241. Thus, the rotating member 600 can be rotatably installed between the first curved 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, thereby compressing the first elastic component 71; when the skin care device is separated from the skin, the first elastic component 71 elastically recovers to drive the rotating member 600 to extend and reset.

[0077] It can also be understood that, since the rotating member 600 is in contact with the first arc surface 1241 , the first arc surface 1241 can have a good limiting effect on the rotating member 600 during the extension and retraction process of the rotating member 600 .

[0078] In some embodiments, the radius of curvature of the first curved surface 1241 can be equal to the radius of the mounting shaft 62. Alternatively, the radius of curvature of the first curved surface 1241 can be greater than the radius of the mounting shaft 62, which is not limited in this embodiment of the present application. 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 can abut against different positions of the first curved 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.

[0079] As mentioned above, in some embodiments, the shell 100 can be provided with a mounting hole 122 and a mounting groove 124, the rotating member body 61 is passed through the mounting hole 122, and partially protrudes 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, then the groove wall of the mounting groove 124 can form a first arc surface 1241.

[0080] 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 that is closer to the rotating member 600 and abuts against a side of the rotating member 600 that is away from the first arcuate surface 1241. Thus, the first floating member 712 can form a more stable and reliable contact with the rotating member 600.

[0081] The surface of the first floating member 712 that contacts the rotating member 600 is flat, so that the first elastic member 71 forms a line contact with the rotating member 600. This prevents excessive friction caused by an excessively large contact area between the first floating member 712 and the rotating member 600.

[0082] Optionally, the surface of one side of the first floating member 712 that contacts the rotating member 600 may also be a curved surface, which is not limited in the embodiment of the present application.

[0083] 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 this embodiment of the present application does not limit this.

[0084] 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.

[0085] For example, there are two mounting shafts 62 and at least two first elastic components 71 . Each mounting shaft 62 abuts against a first elastic component 71 , so that the installation of the rotating member 600 is more stable and reliable.

[0086] 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 according to an embodiment of the present application. 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 this embodiment of the present application.

[0087] In some embodiments, the skin care device may include a bracket assembly 34. The bracket assembly 34 is disposed within the housing 100 and is used to secure 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, although this embodiment of the present application is not limited thereto.

[0088] 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 .

[0089] 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 that 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 (e.g., the mounting shaft 62 of the rotating member 600). Thus, the torsion spring can push the rotating member 600 in a direction extending out of the housing 100.

[0090] In some embodiments, the rotating member 600 is detachably mounted on the housing 100 , thereby making it convenient for the user to disassemble the rotating member 600 for maintenance such as cleaning and replacement.

[0091] Please continue to refer to Figure 10 , Figure 10 for Figure 7 Schematic diagram of the structure of the first elastic component from another perspective. 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 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, thereby being 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 component 72, so that the rotating member 600 can compress the second elastic component 72 and thereby move axially to a disassembled state. When the rotating member 600 moves to the disassembled state, the rotating member 600 can detach from the mounting hole 122 to the outside of the housing 100.

[0092] 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 so as to partially protrude outside the light exiting area 121. The mounting shaft 62 is connected to the rotating member body 61 and is rotatably mounted on the housing 100.

[0093] Then, the mounting shaft 62 can be disposed inside the housing 100, with the end surface of at least one mounting shaft 62 abutting against the second elastic component 72. When the rotating member 600 moves to the disassembled state, the mounting shaft 62 opposite the compressed second elastic component 72 is exposed at the mounting hole 122, thereby allowing it to be removed from the mounting hole 122 to the outside of the housing 100.

[0094] 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 of the disassembly processes of the rotating member 600 can be as follows:

[0095] 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 to leak 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 shell 100; finally, take out the rotating member body 61 tilted in the upper left direction so that the mounting 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.

[0096] 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 in contact with 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, making the disassembly of the rotating member 600 more convenient.

[0097] In some embodiments, the rotating member body 61 is provided with an anti-slip structure, and the anti-slip structure is at least partially located outside the housing 100. Therefore, when the user moves the rotating member body 61 axially, the anti-slip structure can increase the friction between the user and the rotating member body 61, making it easier for the user to move the rotating member body 61.

[0098] For example, the anti-slip structure may include anti-slip stripes arranged around the circumference of the rotating member body 61. Optionally, the anti-slip structure may also include a silicone member sleeved on the rotating member body 61, which is not limited in this embodiment of the present application.

[0099] 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 .

[0100] The second elastic member 721 may include at least one of a coil compression spring, a disc spring, and a leaf spring.

[0101] For example, a vertical plate 126 is protruded from the inner surface of the housing 100 and 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.

[0102] In some embodiments, the skin care device includes a first elastic member 71, which is used to push 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. Continuing with the example of a rotating member body 61 with a mounting shaft 62 at each end along the left-right direction, and with the mounting hole 122 opening facing upward, one possible disassembly process for the rotating member 600 can be as follows:

[0103] First, the rotating member body 61 is pushed rightward, so that the mounting shaft 62 at the left end of the rotating member body 61 moves to be exposed from the mounting hole 122. At this time, the second elastic member 72 at the right end of the rotating member body 61 is compressed. Then, 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. At this time, the mounting shaft 62 at the right end of the rotating member body 61 is correspondingly moved downward. The first elastic member 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 upward and the right end facing downward. Finally, the rotating member body 61 is removed 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 removal of the rotating member 600. Conversely, the rotating member 600 can be installed.

[0104] In some embodiments, the 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, the first elastic member 71 can be prevented from interfering with the second elastic member 72 when elastically recovering after being compressed, thereby preventing the rotating member 600 from being tightened.

[0105] As mentioned above, the first elastic component 71 includes, for example, a first elastic member 711 and a first floating member 712. The first floating member 712 is disposed on the side of the first elastic member 711 closest to the rotating member 600 and abuts against the circumferential surface of the rotating member 600. 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 the side of the second elastic member 721 closest to the rotating member 600 and abuts against the end surface of the mounting shaft 62. In this case, along the axial direction of the rotating member body 61, the orthographic projection of the first floating member 712 and at least a portion of the orthographic projection of the first elastic member 711 can both be located within the orthographic projection of the second floating member 722.

[0106] In some embodiments, the skin care device further includes a contact detection module, which is disposed within the housing 100 and is configured to detect contact between the light-emitting surface 123 and the skin to be treated. The contact detection module may include a skin contact detection circuit, which may employ any conventional contact detection circuit and is not limited in this embodiment.

[0107] It is understandable that, because the rotating member 600 partially protrudes from the light-emitting surface 123, a gap is likely to exist between the light-emitting surface 123 and the skin to be treated after the rotating member 600 abuts the skin to be treated. This 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 present application, when the fit detection module detects that the skin care device and the skin to be treated are not in fit, the skin care device can take corresponding processing actions, such as controlling the light-emitting component 200 to stop emitting light, notifying the user that the skin is not in fit, etc., and the embodiment of the present application is not limited to this.

[0108] In some embodiments, the fit detection module can be electrically connected to the rotating member 600 to detect the fit between the skin care device and the skin to be treated via the rotating member 600. Therefore, it can also be understood that the rotating member 600 can be reused as the detection electrode of the fit detection module to reduce the number of components required for the light emitting surface 123, thereby reducing the area of ​​the light emitting surface 123, making it easier for the user to easily and accurately fit the light emitting area 121 to the skin to be treated.

[0109] Exemplarily, the rotating member 600 is a conductive member to form a detection electrode.

[0110] For example, the rotating member 600 can 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.

[0111] 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.

[0112] For example, the conductive layer can be formed on the rotating member 600 by spraying, evaporation, electroplating, etc., which is not limited in the present embodiment. In the actual manufacturing process, only the conductive layer can be made of a 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.

[0113] Optionally, the rotating member 600 includes a conductive sheet, which is electrically connected to the lamination detection module to form a detection electrode.

[0114] For example, the conductive sheet can be attached to the rotating member 600 by means of clipping, screwing, welding, etc., which is not limited in the present embodiment. In the actual manufacturing 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 low cost, easy manufacturing, wear resistance, etc. according to actual needs.

[0115] In some embodiments, the skin care device further includes a first elastic component 71, which is made of a conductive material. The first elastic component 71 is electrically connected to the fit detection module and also abuts against the rotating member 600 to form an electrical connection. Therefore, the fit detection module can be electrically connected to the rotating member 600 through the first elastic component 71 without interfering with the rotation of the rotating member 600. Furthermore, during the rotation of the rotating member 600, even if the rotating member 600 and / or the first elastic component 71 undergo some wear, the first elastic component 71, driven by its own elastic force, can remain firmly against the rotating member 600, thereby ensuring the reliability and stability of the electrical connection.

[0116] 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.

[0117] For example, Figure 8 As mentioned above, the skin care device may include a bracket assembly 34. The bracket assembly 34 is disposed within the housing 100 and is used to secure at least one of the cold compress assembly 400 and the light output assembly 200. The first elastic member 71 may be mounted on the bracket assembly 34 or on the inner surface of the housing 100, but this embodiment of the present application is not limited thereto.

[0118] 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 .

[0119] 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 that is sleeved on the mounting post 3431. One torsion arm of the torsion spring presses against the reinforcing rib 3432 and is electrically connected to the fit detection module, while the other torsion arm of the torsion spring presses against the rotating member 600, thereby achieving electrical connection between the fit detection module and the rotating member 600.

[0120] It can also be understood that the first elastic component 71 can press the rotating member 600 against the inner surface of the shell 100, or can press the rotating member 600 against other components inside the shell 100. This embodiment of the present application does not limit this.

[0121] 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 component 71) from being separated from the mounting post 3431. The side of the rotating member 600 that is closer to the light exit area 121 in the circumferential direction is supported by the first mounting plate 345, and the side of the rotating member 600 that is away from the light exit area 121 in the circumferential direction abuts against the torsion spring, so that the rotating member 600 is rotatably disposed on the first mounting plate 345. Therefore, during 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.

[0122] 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 is sleeved onto the end of the rotating member 600 facing away from the mounting post 3431 to form a rotational connection. This allows both ends of the rotating member 600 to be supported and secured, ensuring more stable and reliable rotation of the rotating member 600.

[0123] 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.

[0124] The above are some examples of the rotating part 600 being reused as a detection electrode in the embodiment of the present application. It should be understood that when the rotating part 600 is not reused as a detection electrode, it can also be installed using the above structure, and the embodiment of the present application does not limit this.

[0125] Please continue to refer to Figure 11 , Figure 11 for Figure 2 Optionally, the skin care device may further include a fit detection component 800. The fit detection component 800 is disposed at the light emitting area 121 to collect a fit status signal between the light emitting surface 123 and the skin to be treated.

[0126] In some embodiments, both 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 come into contact with the skin being treated and roll over the skin. Simultaneously, the fit detection component 800 can cooperate with the skin being treated to collect a signal indicating the fit between the skin care device and the skin being treated.

[0127] In some embodiments, the fit detection component 800 may be electrically connected to a fit detection circuit for determining the fit state between the light emitting surface 123 and the skin to be treated based on the fit state signal.

[0128] Illustratively, 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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 status signal for the fit detection circuit to determine whether the skin care device fits the skin to be treated.

[0133] 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.

[0134] Exemplarily, the number of the rotating members 600 and the number of the fitting detection components 800 are 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 .

[0135] Therefore, compared to the case where the fitting detection component 800 is located on the side of the rotating part 600 away from the light emitting area 121, or the case where the rotating part 600 is located on the side of the fitting detection component 800 away from the light emitting area 121, in the embodiment of the present application, both the rotating part 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 to the skin to be treated.

[0136] In some embodiments, there are at least two rotating members 600, with one rotating member 600 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 friction between the skin care device and the skin to be treated.

[0137] In some embodiments, a fit detection component 800 is provided on each side of the light exit area 121 along the length direction. Thus, more space can be reserved on both sides of the light exit area 121 along the width direction to install a longer rotating member 600, thereby reducing the friction between the skin care device and the skin to be treated.

[0138] 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.

[0139] For example, the prompt component can be electrically connected to the fit detection circuit and used to indicate the fit status 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, thereby prompting the user to promptly fit the light-emitting surface 123 of the skin care device to the skin to be treated to improve the care effect.

[0140] Please continue to refer to Figure 12 , Figure 12 This is a schematic diagram of the structure of a rotation detection component provided in an embodiment of the present application. In some embodiments, the skin care device further includes a rotation detection component 900. The rotation detection component 900 is disposed within the housing 100 and is used to detect the rotational speed and / or rotational angle of the rotating member 600. Thus, information such as the speed and distance of movement of the skin care device on the treated skin can be conveniently determined based on the rotational speed and / or rotational angle of the rotating member 600.

[0141] In some embodiments, the skin care device may further include a controller electrically connected to the rotation detection component 900 and the light output assembly 200. The controller is configured to control the operating state of the light output assembly 200 based on the rotation information parameters of the rotating member 600, wherein the rotation information parameters include the rotation speed and / or rotation angle of the rotating member 600.

[0142] Exemplarily, the controller is configured to determine a target light frequency for the light emitting assembly 200 based on the rotational speed of the rotating member 600 and set the current light frequency of the light emitting assembly 200 as the target light frequency. This allows the skin care device to emit light at a more appropriate frequency during movement, thereby improving the skin care effect.

[0143] In some embodiments, the controller is configured to control the light emitting assembly 200 to emit light a preset number of times each time 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.

[0144] As mentioned above, in some embodiments, the skin care device may further include a prompting component, such as an indicator light, a display screen, or a voice module. The controller may also be electrically connected to the prompting component. The controller is configured to control the prompting component to alert the user when the rotational speed of the rotating member 600 exceeds a preset value. This prevents the skin care device from moving too quickly, potentially preventing the light output assembly 200 from providing care to the skin being treated.

[0145] In some embodiments, 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 this embodiment of the present application.

[0146] For example, when the rotation detection component 900 includes a photoelectric sensor, the rotating part 600 may be provided with a trigger part that cooperates with the photoelectric sensor, and the photoelectric sensor is arranged on the rotation path of the trigger part, so that every time the rotating part 600 rotates a certain angle, the trigger part can trigger the photoelectric sensor to detect the rotation angle and / or rotation speed of the rotating part 600.

[0147] When the rotation detection component 900 includes an encoder, the encoder's roller may abut against the rotating member 600 , so that the rotating member 600 can drive the encoder's roller to rotate to detect the rotation angle and / or rotation speed of the rotating member 600 .

[0148] Please continue to refer to Figure 13 , Figure 13 for Figure 12 Exploded diagram. 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 in response to 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 rational distribution of components inside the housing 100.

[0149] In some embodiments, the driven wheel 91 is provided with at least one magnetic part 911, and the rotation sensor 92 includes a Hall sensor to cooperate with the magnetic part 911 of the driven wheel 91 to detect the rotation speed and / or rotation angle of the rotating part 600, so that the rotation sensor 92 has the advantages of high sensitivity and stable signal output.

[0150] In some embodiments, there are multiple magnetic members 911, which are evenly spaced along the circumference of the driven wheel 91. Thus, by cooperating with the Hall sensor and the multiple magnetic members 911, multiple rotation angles of the multiple rotating members 600 can be detected.

[0151] As mentioned above, the skin care device may further include a bracket assembly 34, which is disposed within the housing 100 and is mounted 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 to 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. Hiding the driven wheel 91 between the bracket assembly 34 and the driven wheel 91 provides a degree of protection, preventing other components from interfering with its rotation.

[0152] In some embodiments, one end of the rotating member 600 is rotatably mounted on the second mounting plate 346 , thereby making the installation of the rotating member 600 more stable.

[0153] 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, thereby reducing the geometric tolerances between the driven wheel 91 and the rotating member 600.

[0154] In some embodiments, the rotation detection component 900 further includes a second mounting pin 94, which is disposed on the second mounting plate 346. The rotation detection component 900 further includes a transmission wheel 95 that is 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 a transmission manner, so that the transmission wheel 95 can rotate with the rotating member 600, thereby driving the driven wheel 91 to rotate. Thus, by adding the transmission wheel 95, the driven wheel 91 can be flexibly disposed at different positions within the housing 100, thereby facilitating the rational distribution of components within the housing 100.

[0155] Of course, the driven wheel 91 may also be in direct contact with the rotating member 600 to form a transmission connection, that is, the rotation detection component 900 may not include the above-mentioned transmission wheel 95, and the embodiment of the present application does not limit this.

[0156] In some embodiments, one side surface of the driven wheel 91 in the thickness direction is disposed opposite to the cold compress assembly 400 .

[0157] It is understandable that in order to improve the cooling effect of the cold compress assembly 400, the cold compress assembly 400 is generally larger. 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 larger to increase the contact area between the light guide component 41 and the cooling plate 42. Based on this, in the embodiment of the present application, one side surface of the driven wheel 91 in the thickness direction is arranged to face the cold compress assembly 400, which can fully utilize the larger space on the outer peripheral side of the cold compress assembly 400 to facilitate the miniaturization design of the skin care device.

[0158] 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 the cold compress component 400, the distance between the driven wheel 91 and the rotating part 600 can be made closer, thereby avoiding the transmission chain between the driven wheel 91 and the rotating part 600 being too long, and thus improving the accuracy of the detection results of the rotation detection component 900.

[0159] 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, thereby making full use of the larger space on the outer peripheral side of the cold compress assembly 400 to facilitate the miniaturized design of the skin care device.

[0160] 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.

[0161] 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.

[0162] 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 understood that the wavelength of light required for skin care devices to perform photorejuvenation and hair removal on the skin being treated is generally between 460 nanometers and 1200 nanometers. Since most of the light generated by the light output assembly 200 has a wavelength below 1200 nanometers, the filter assembly 1000 can filter out the required light for hair removal and photorejuvenation.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] It is also understood that the skin care device may further include a controller, which is electrically connected to the driving component and the light output component 200. The controller is configured to control the operating state of the light output component 200 based on the operating information of the driving component, or to control the operating state of the driving component based on the operating information of the light output component 200.

[0167] Exemplarily, the controller is configured to: determine the movement information parameters of the skin care device on the skin to be treated based on the working information of the driving component, and the movement information parameters may include at least one of 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.

[0168] 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, which is not limited in this embodiment of the present application.

[0169] 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.

[0170] 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 this embodiment of the present application does not limit this.

[0171] The above is a detailed introduction to the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, based on the ideas of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
