[0068] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0069] Please refer to Figure 1 This application provides a skin care device 100, which can be a light-based skin care device, such as a hair removal device or a skin rejuvenation device, so that the skin care device 100 has a light care function.
[0070] Phototherapy involves irradiating the skin to be treated with IPL light sources, laser light sources, or LED light sources.
[0071] Of course, the skin care device 100 may also have an electrostimulation care function, making the skin care device 100 a multifunctional skin care device 100 with at least a light-based care function and an electrostimulation care function. This application embodiment does not limit this.
[0072] Electrical stimulation care can be performed by applying electrical stimulation currents such as radiofrequency current, intermediate frequency current, and microcurrents (such as EMS current) to the skin to be treated.
[0073] Below, we will first introduce the skin care device 100 with a light care function as an example.
[0074] Please continue to refer to this. Figure 2 The skin care device 100 may include a main housing 11 and a light-emitting assembly 12. The main housing 11 is provided with a light-emitting hole 111. The light-emitting assembly 12 is disposed inside the main housing 11 and is used to generate light that is emitted from the light-emitting hole 111 onto the skin to be treated. Thus, the light-emitting assembly 12 can provide phototherapy to the skin to be treated through the light-emitting hole 111.
[0075] The light emission hole 111 can be disposed on one end face of the main housing 11 along its length, or it can be disposed on the peripheral surface of the main housing 11. This application embodiment does not limit this.
[0076] In some embodiments, the light-emitting component 12 may include a light source 121.
[0077] The light source 121 may include a lamp tube, such as a xenon lamp tube, etc., and this application embodiment does not limit this. Of course, in some other embodiments, the light emitting component 12 may also include a laser light source, etc., and this application embodiment does not limit this either.
[0078] The number of light sources 121 can be one or more, and this application embodiment does not limit this.
[0079] Please combine Figure 2 and Figure 3 The light-emitting assembly 12 may further include a reflective component 122. The reflective component 122 has an inner cavity 1221 and an outlet 1222. The light source 121 is at least partially disposed in the inner cavity 1221, and the outlet 1222 communicates with the side of the inner cavity 1221 facing the light-emitting aperture 111, so that the reflective component 122 is used to reflect the light emitted by the light source 121 toward the light-emitting aperture 111. Thus, the reflective component 122 can reflect a portion of the light emitted by the light source 121 to the light-emitting aperture 111, thereby increasing the intensity of the light emitted from the light-emitting aperture 111.
[0080] For example, the light source 121 may include a lamp tube, and the reflector 122 may include an arc-shaped portion. The arc-shaped portion surrounds the outer periphery of the lamp tube, the inner circumferential surface of the arc-shaped portion forms an inner cavity 1221, and an outlet 1222 is formed between the two circumferential edges of the arc-shaped portion.
[0081] It is understood that the lamp tube may be partially disposed within the inner cavity 1221, for example, with both ends of the lamp tube located outside the arc-shaped portion to facilitate electrical connection and installation of the lamp tube. Optionally, the lamp tube may also be completely located within the inner cavity 1221, and this embodiment of the application does not limit this.
[0082] In some embodiments, the skin care device 100 further includes a first light-transmitting element 131. The first light-transmitting element 131 is disposed at the light-emitting hole 111 and includes a light-emitting surface 1311 and a light-incident surface 1312. The light-emitting surface 1311 and the light-incident surface 1312 are disposed opposite to each other. The light-emitting surface 1311 is used to adhere to the skin to be treated, and the light-incident surface 1312 is disposed facing the light-emitting assembly 12. Therefore, the light generated by the light-emitting assembly 12 can enter the first light-transmitting element 131 from the light-incident surface 1312, and then be directed from the light-emitting surface 1311 onto the skin to be treated for phototherapy.
[0083] In some embodiments, the first light-transmitting element 131 also functions as a cooling compress element, thereby enabling the skin care device 100 to also have a cooling compress function. Furthermore, the first light-transmitting element 131 can reduce or even eliminate the heat generated during the phototherapy treatment of the skin by the skin care device 100, thereby improving the user experience.
[0084] For example, such as Figure 3 As shown, the skin care device 100 may include a cold compress component 13, which is used to apply a cold compress to the treated skin.
[0085] Accordingly, the cooling compress assembly 13 may include a cooling element 132 and a first light-transmitting element 131. The cooling element 132 is thermally connected to the first light-transmitting element 131. Thus, the cooling compress assembly 13 can apply a cooling compress to the skin to be treated through the first light-transmitting element 131.
[0086] The first light-transmitting element 131 may include sapphire, glass, acrylic, etc., and this application embodiment does not limit it.
[0087] Next, we will continue with the introduction in conjunction with the incident light plane 1312.
[0088] Please continue to refer to this. Figure 4 In some embodiments, the light-incident surface 1312 is convex, so that the first light-transmitting element 131 is used to focus and transmit the light generated by the light-emitting component 12 to the skin to be treated.
[0089] Since the light-incident surface 1312 of the first light-transmitting element 131 is convex, the first light-transmitting element 131 can focus and transmit the light generated by the light-emitting component 12 to the skin to be treated, thereby making the energy intensity of the light emitted by the light-emitting component 12 to the skin to be treated higher, and ultimately improving the skin care effect.
[0090] In some embodiments, the light-incident surface 1312 is a convex curved surface. Therefore, the first light-transmitting element 131 can be understood as forming a convex lens, so that the first light-transmitting element 131 has the function of focusing light.
[0091] In some embodiments, the light-incident surface 1312 is a cylindrical arc surface. That is, the light-incident surface 1312 is part of the peripheral surface of a virtual cylinder, thereby allowing the light-incident surface 1312 to direct the incident light rays toward the axis of the virtual cylinder.
[0092] Please combine them together Figure 4 and Figure 5 In some embodiments, at least 75% of the orthographic projection of the light-incident surface 1312 on the plane where the light-emitting aperture 111 is located coincides with the orthographic projection of the emission port 1222. This allows the light-incident surface 1312 to receive most of the light emitted from the light-emitting assembly 12 through the emission port 1222, thereby improving the light-emitting efficiency of the light-emitting assembly 12. This results in a higher energy intensity of the light emitted by the light-emitting assembly 12 towards the skin to be treated, ultimately improving the skincare effect.
[0093] For example, on the plane where the light exit hole 111 is located, the 75%, 77.5%, 81.2%, 84%, 87.5%, 90%, 91.2%, 93%, 93.8%, 94%, 95%, 96.32%, 97%, 98.8%, 99%, or 100% regions of the orthogonal projection of the light incident surface 1312 coincide with the orthogonal projection of the light exit hole 1222. This embodiment of the application does not limit this.
[0094] It should be noted that the outer surface of the main unit housing 11 may have a first plane 112, and the light emission hole 111 is disposed on the first plane 112. Therefore, in this application, the plane on which the first plane 112 is located is the plane on which the opening of the light emission hole 111 is located.
[0095] On the plane where the light-emitting aperture 111 is located, the ratio of the area of the orthographic projection of the emission port 1222 to the area of the orthographic projection of the incident surface 1312 is greater than or equal to 0.8 and less than or equal to 1.2. Therefore, it can also be understood that on the plane where the light-emitting aperture 111 is located, the areas of the orthographic projection of the emission port 1222 and the orthographic projection of the incident surface 1312 are approximately the same, so that most of the light emitted from the inner cavity 1221 of the reflective component 122 can enter the first light-transmitting component 131 from the incident surface 1312, thereby making the energy intensity of the light emitted by the light-emitting component 12 directed towards the skin to be treated higher, and ultimately improving the skin care effect.
[0096] For example, on the plane where the light outlet 111 is located, the ratio of the area of the orthographic projection of the light outlet 1222 to the area of the orthographic projection of the light incident surface 1312 is 0.8, 0.84, 0.89, 0.9, 0.92, 0.95, 0.96, 0.975, 0.99, 1, 1.02, 1.05, 1.1, 1.12, 1.14, 1.15, 1.18, 1.19 or 1.2. This application embodiment does not limit this ratio.
[0097] In some embodiments, the ratio of the area of the orthographic projection of the exit port 1222 to the area of the orthographic projection of the incident surface 1312 on the plane where the opening of the light exit hole 111 is located is greater than or equal to 0.9 and less than or equal to 1.1.
[0098] It can also be understood that when at least 75% of the orthographic projection of the incident surface 1312 on the plane where the light outlet 111 is located coincides with the orthographic projection of the outlet 1222, and the ratio of the area of the orthographic projection of the outlet 1222 to the area of the incident surface 1312 is 0.8 to 1.2, it can be understood that on the plane where the light outlet 111 is located, the orthographic projection of the incident surface 1312 and the orthographic projection of the outlet 1222 of the reflective component 122 roughly coincide and their areas are roughly equal. That is, the incident surface 1312 roughly blocks the outlet of the reflective component 122, thereby allowing most of the light emitted from the inner cavity 1221 of the reflective component 122 to enter the first light-transmitting element 131 from the incident surface 1312, thus making the energy intensity of the light emitted by the light-emitting component 12 toward the skin to be treated higher, and ultimately improving the skin care effect.
[0099] In some embodiments, the vertex of the light-incident surface 1312 faces the middle of the light-outceasing aperture 111 along its length.
[0100] As mentioned above, the first light-transmitting element 131 can be understood as a convex lens with focusing function. The optical axis of the convex lens typically passes through the vertex of the light-incident surface 1312. Therefore, by focusing the light from the vertex of the light-incident surface 1312 towards the center of the light-exit aperture 111 along its length, the convex lens (i.e., the first light-transmitting element 131) can converge the light towards the center of the light-exit aperture 111, thereby increasing the energy intensity of the light emitted by the light-exiting assembly 12 onto the skin to be treated, ultimately improving the skincare effect.
[0101] In some embodiments, the vertex of the light-incident surface 1312 faces the middle of the lamp tube along its length.
[0102] It is understandable that the brightness at both ends of the lamp tube along its length is usually lower than that in the middle. Therefore, by having the apex of the light-incident surface 1312 face the brighter middle part of the lamp tube, it can be ensured that most of the light generated by the lamp tube can be incident from the light-incident surface 1312 onto the first light-transmitting element 131, thereby increasing the energy intensity of the light emitted by the output light assembly 12 onto the skin to be treated, and ultimately improving the skin care effect.
[0103] When the vertex of the light-incident surface 1312 is simultaneously aligned with the middle of the lamp tube and the middle of the light-out aperture 111, the middle of the lamp tube and the middle of the light-out aperture 111 are both approximately located on the optical axis of the first light-transmitting element 131. This allows the first light-transmitting element 131 to focus most of the light generated by the lamp tube into the light-out aperture 111, thereby increasing the energy intensity of the light emitted from the light-out aperture 111 onto the skin to be treated.
[0104] In some embodiments, the length direction of the outlet 1222 is the same as the length direction of the lamp tube. This allows the reflector 122 to reflect light generated in a larger area along the length direction of the lamp tube toward the incident surface 1312, thereby increasing the energy intensity of the light emitted from the outlet 111 toward the skin to be treated.
[0105] like Figure 5 As shown, in some embodiments, along the length of the lamp tube, the ratio of the length L1 of the light-incident surface 1312 to the length L2 of the light-outlet 1222 is greater than or equal to 0.8 and less than or equal to 1.2.
[0106] Therefore, it can also be understood that along the length of the lamp tube, the length L1 of the light-incident surface 1312 and the length L2 of the outlet 1222 of the reflector 122 are approximately the same. This allows most of the light emitted from the inner cavity 1221 of the reflector 122 to enter the first light-transmitting element 131 through the light-incident surface 1312, thereby making the energy intensity of the light focused and transmitted to the skin to be treated by the first light-transmitting element 131 higher, and ultimately improving the skin care effect.
[0107] For example, along the length of the lamp tube, the ratio of the length L1 of the light-incident surface 1312 to the length L2 of the light-outlet 1222 is 0.8, 0.84, 0.89, 0.9, 0.92, 0.95, 0.96, 0.975, 0.99, 1, 1.02, 1.05, 1.1, 1.12, 1.14, 1.15, 1.18, 1.19 or 1.2, and the embodiments of this application do not limit this ratio.
[0108] In some embodiments, the ratio of the length L1 of the light-incident surface 1312 to the length L2 of the light-outlet 1222 along the length of the lamp tube is greater than or equal to 0.9 and less than or equal to 1.0.
[0109] In some embodiments, at least one edge of the outlet 1222 along its length is flush with the incident light surface 1312. This allows most of the light generated by the lamp to enter the first light-transmitting element 131 from the incident light surface 1312, thereby increasing the energy intensity of the light emitted by the light-emitting assembly 12 towards the skin to be treated, ultimately improving the skin care effect.
[0110] That is to say, one side edge of the outlet 1222 along its length can be flush with the convex surface, or both sides of the outlet 1222 along its length can be flush with the convex surface. Of course, in some other embodiments, each side edge of the outlet 1222 along its length can be non-flush with the convex surface, and this application embodiment does not limit this.
[0111] Please continue to refer to this. Figure 6 In some embodiments, the width direction of the emission port 1222 intersects the length direction of the lamp tube, and the width direction of the light-incident surface 1312 is the same as the width direction of the emission port 1222.
[0112] For example, the length direction of the lamp tube is the width direction of the skin care device 100, the width direction of the outlet 1222 is the thickness direction of the skin care device 100, and the width direction of the light incident surface 1312 is also the thickness direction of the skin care device 100.
[0113] In some embodiments, the ratio of the width L3 of the exit port 1222 to the width L4 of the incident surface 1312 is greater than or equal to 0.8 and less than or equal to 1.2.
[0114] Therefore, it can be understood that the width L3 of the outlet 1222 is approximately the same as the width L4 of the incident surface 1312, so that most of the light emitted from the inner cavity 1221 of the reflective component 122 can enter the first light-transmitting component 131 through the incident surface 1312, thereby making the energy intensity of the light focused and transmitted to the skin to be treated by the first light-transmitting component 131 higher, and ultimately improving the skin care effect.
[0115] For example, the ratio of the width L3 of the exit port 1222 to the width L4 of the incident surface 1312 is 0.8, 0.84, 0.89, 0.9, 0.92, 0.95, 0.96, 0.975, 0.99, 1, 1.02, 1.05, 1.1, 1.12, 1.14, 1.15, 1.18, 1.19 or 1.2, and the embodiments of this application do not limit this ratio.
[0116] In some embodiments, the ratio of the width L3 of the exit port 1222 to the width L4 of the incident surface 1312 is greater than or equal to 0.9 and less than or equal to 1.0.
[0117] In some embodiments, at least one edge of the outlet 1222 in the width direction is flush with the incident surface 1312. This allows most of the light generated by the lamp to enter the first light-transmitting element 131 from the incident surface 1312, thereby increasing the energy intensity of the light focused and transmitted to the skin by the first light-transmitting element 131, ultimately improving the skin care effect.
[0118] That is to say, one side edge of the exit port 1222 in the width direction may be flush with the light-incident surface 1312, or both sides of the exit port 1222 in the width direction may be flush with the light-incident surface 1312. Of course, in some other embodiments, each side edge of the exit port 1222 in the width direction may not be flush with the light-incident surface 1312, and this application embodiment does not limit this.
[0119] Please continue to refer to this. Figure 5 In some embodiments, the radius of curvature of the light-incident surface 1312 is greater than or equal to 30 mm and less than or equal to 40 mm.
[0120] Understandably, the radius of curvature of the light-incident surface 1312 affects the focal length of the first light-transmitting element 131. For example, when the radius of curvature of the light-incident surface 1312 is too large, the focal length of the first light-transmitting element 131 will increase accordingly. As a result, with a fixed distance between the light-incident surface 1312 and the light-emitting surface 1311, the light at the light-emitting surface 1311 will still be relatively diffuse, leading to lower light energy intensity at the light-emitting surface 1311. When the radius of curvature of the light-incident surface 1312 is too large, the focal length of the first light-transmitting element 131 will decrease accordingly. As a result, with a fixed distance between the light-incident surface 1312 and the light-emitting surface 1311, although the light energy at the light-emitting surface 1311 is higher, the light spot area at the light-emitting surface 1311 will be too small, resulting in low treatment efficiency for larger areas of skin.
[0121] Therefore, in this embodiment of the application, the radius of curvature of the light-incident surface 1312 is controlled between 30 mm and 40 mm, which can ensure that the light intensity at the light-outceasing surface 1311 is strong enough and also ensure the skin care efficiency of the skin care device 100, thereby improving the user experience.
[0122] For example, the radius of curvature of the light-incident surface 1312 is 30 mm, 32 mm, 33.4 mm, 35 mm, 36.3 mm, 37 mm, 37.5 mm, 38 mm, 38.9 mm, 39 mm, 39.1 mm, 39.5 mm or 40 mm, and this application embodiment does not limit it.
[0123] In some embodiments, the central angle γ of the incident surface 1312 is greater than or equal to 70° and less than or equal to 100°.
[0124] Therefore, it can avoid the light-incident surface 1312 being too large and wasting too much space in the main unit housing 11, and it can also avoid the light-incident surface 1312 being too small and causing too much light from the light-emitting component 12 to be unable to enter the first light-transmitting element 131 from the light-incident surface 1312.
[0125] Therefore, in this embodiment of the application, the central angle γ of the light-incident surface 1312 is controlled between 70° and 100°, which can ensure that the light intensity at the light-out surface 1311 is strong enough, and also avoid the skin care device 100 from being too large.
[0126] For example, the central angle γ of the incident light surface 1312 is 70°, 73°, 75°, 76°, 78.1°, 79°, 79.5°, 80°, 82°, 83.5°, 85°, 87°, 88.1°, 89°, 90°, 91°, 94.5°, 95°, 96°, 97.8°, 99° or 100°, and the embodiments of this application do not limit this.
[0127] In some embodiments, the central angle γ of the incident surface 1312 is greater than or equal to 80° and less than or equal to 90°.
[0128] The above is a description of the light-incident surface 1312 in the embodiments of this application. The embodiments of this application will continue to be described in conjunction with the light-outceasing surface 1311.
[0129] In some embodiments, the distance L5 from the vertex of the incident light surface 1312 to the emitting light surface 1311 is greater than or equal to 5 mm and less than or equal to 25 mm.
[0130] Understandably, if the distance L5 from the vertex of the light-incident surface 1312 to the light-exiting surface 1311 is too large, the first light-transmitting element 131 will occupy more space in the main housing 11, which is not conducive to the miniaturization design of the skin care device 100. If the distance L5 from the vertex of the light-incident surface 1312 to the light-exiting surface 1311 is too small, the radius of curvature of the light-incident surface 1312 will also be limited, resulting in a weaker light-gathering ability of the light-incident surface 1312, which ultimately leads to a lower light energy intensity at the light-exiting surface 1311.
[0131] Therefore, in this embodiment of the application, the distance L5 from the vertex of the light-incident surface 1312 to the light-exiting surface 1311 is controlled between 5 mm and 25 mm, which can ensure that the light intensity at the light-exiting surface 1311 is strong enough, and also avoid the skin care device 100 from being too large.
[0132] For example, the distance L5 from the vertex of the light-incident surface 1312 to the light-exit surface 1311 is 5 mm, 6.5 mm, 7 mm, 8.4 mm, 9 mm, 9.75 mm, 10 mm, 11 mm, 13.4 mm, 14 mm, 15 mm, 16.7 mm, 18 mm, 18.5 mm, 19 mm, 19.9 mm, 20 mm, 21 mm, 23.2 mm, 24 mm, 24.5 mm, or 25 mm. This application embodiment does not limit this.
[0133] The distance L5 from the vertex of the incident light surface 1312 to the exit light surface 1311 is greater than or equal to 10 mm and less than or equal to 20 mm.
[0134] In some embodiments, the light-emitting surface 1311 is a flat surface, a slightly concave surface, or a slightly convex surface. Therefore, the light-emitting surface 1311 can better conform to the surface of the skin to be treated, thereby improving the skin care effect of the skin care device 100.
[0135] In some embodiments, the orthographic projection of the light-emitting surface 1311 is positioned close to the center of the orthographic projection of the light-incident surface 1312 on the plane where the light-emitting aperture 111 is located. Furthermore, the light-incident surface 1312 can more accurately focus the light from the light-emitting assembly 12 onto the light-emitting surface 1311, thereby increasing the energy intensity of the light at the light-emitting surface 1311 and ultimately improving the skincare effect.
[0136] In some embodiments, the light-emitting surface 1311 is disposed near the middle of the light-emitting component 12 along the length direction of the light-emitting component 12.
[0137] Understandably, taking a light tube as an example, the light intensity in the middle of the tube is greater than that at both ends. Therefore, when the middle part of the light-emitting component 12, which has a higher light intensity, is aligned with the middle part of the light-emitting surface 1311, the intensity of the light emitted by the light-emitting component 12 towards the light-emitting surface 1311 can be higher, ultimately improving the skin care effect.
[0138] For example, along the length of the light-emitting assembly 12, the first light-transmitting element 131 is positioned near the center of the light-emitting assembly 12, so that both the light-emitting surface 1311 and the light-incident surface 1312 are positioned near the center of the light-emitting assembly 12. Therefore, in the plane where the opening of the light-emitting aperture 111 is located, the orthographic projection of the light-emitting surface 1311 is also positioned near the center of the orthographic projection of the light-incident surface 1312.
[0139] Therefore, the light emitted by the light-emitting component 12 can be incident from the light-incident surface 1312 to the first light-transmitting element 131 to the maximum extent, and then converge at the light-emitting surface 1311 and be directed toward the skin to be treated, thereby improving the skin care effect.
[0140] In some embodiments, the area of the orthographic projection of the light-incident surface 1312 on the plane where the light-emitting aperture 111 is located is larger than the area of the orthographic projection of the light-emitting surface 1311.
[0141] For example, the cross-sectional area of the first light-transmitting element 131 is reduced along the direction from the light-incident surface 1312 to the light-emitting surface 1311. Furthermore, since the area of the light-emitting surface 1311 is smaller, the end face of the light-emitting hole 111 can also be made smaller, thereby making it easier for the user to accurately attach the light-emitting hole 111 to the user's skin to be treated.
[0142] For example, please refer to Figure 7 and Figure 8One end of the main housing 11 is provided with a shrinkage section 113, and a light emission hole 111 is disposed on the end face of the shrinkage section 113. Along the direction close to the light emission hole 111, the cross-sectional area of the shrinkage section 113 gradually decreases. This allows the end face of the main housing 11 with the light emission hole 111 to be smaller, so that the user can accurately fit the light emission hole 111 onto the user's skin to be treated.
[0143] In some embodiments, the ratio of the orthographic projection of the light-incident surface 1312 to the orthographic projection of the light-outcident surface 1311 on the plane where the light-outcident aperture 111 is located is greater than or equal to 2 and less than or equal to 4.
[0144] This ensures that the light-incident surface 1312 has a sufficiently large area to receive light emitted from the outlet 1222 of the reflector 122, while also preventing the light-emitting surface 1311 from being too large, which would result in low light intensity at various points on the light-emitting surface 1311.
[0145] For example, on the plane where the light-emitting aperture 111 is located, the ratio of the orthographic projection of the light-incident surface 1312 to the orthographic projection of the light-emitting surface 1311 is 2, 2.3, 2.5, 2.67, 2.8, 2.85, 3, 3.13, 3.2, 3.5, 3.64, 3.7, 3.8, 3.89, 3.94 or 4. This application embodiment does not limit this ratio.
[0146] like Figure 7 As shown, in some embodiments, the first light-transmitting element 131 further includes a first side surface 1313 and a second side surface 1314. The first side surface 1313 is connected to one end of the light-incident surface 1312 and one end of the light-exiting surface 1311, respectively. The second side surface 1314 is connected to the other end of the light-incident surface 1312 and the other end of the light-exiting surface 1311, respectively.
[0147] That is, the light-incident surface 1312, the first side surface 1313, the light-exiting surface 1311, and the second side surface 1314 can be connected end to end in sequence.
[0148] The first side 1313, with one end near the light-emitting surface 1311, and the second side 1314, with one end near the light-emitting surface 1311, are inclined toward each other, so that the cross-sectional area of the first light-transmitting element 131 gradually decreases along the direction of the light-incident surface 1312 toward the light-emitting surface 1311.
[0149] In some embodiments, the light source 121 of the light-emitting assembly 12 is a lamp tube, and the first light-transmitting element 131 further includes a first side surface 1313 and a second side surface 1314, which are located along the length of the lamp tube. The first side surface 1313 and the second side surface 1314 connect the light-incident surface 1312 and the light-emitting surface 1311, and the first side surface 1313 and the second side surface 1314 extend inward at an inward angle in the direction from the light-incident surface 1312 to the light-emitting surface 1311.
[0150] Furthermore, the space along the length of the lamp tube in the main housing 11 can be fully utilized to set the light-incident surface 1312, so as to achieve focusing through the convex curved surface of the light-incident surface 1312. This makes it easier to make the main housing 11 smaller in the thickness direction, which is beneficial to the miniaturization of the skin care device 100.
[0151] It should be noted that the first side surface 1313 can be either a curved surface or a flat surface. The second side surface 1314 can also be either a curved surface or a flat surface. Therefore, along the direction from the light-incident surface 1312 to the light-exit surface 1311, the cross-sectional area of the first light-transmitting element 131 can decrease linearly or non-linearly, and this embodiment does not limit this.
[0152] Please continue to refer to this. Figure 9 and Figure 10 In some embodiments, the first light-transmitting element 131 may further include a third side surface 1315 and a fourth side surface 1316. The third side surface 1315 and the fourth side surface 1316 are disposed opposite each other along the thickness direction of the first light-transmitting element 131. Furthermore, the light-incident surface 1312, the first side surface 1313, the light-exit surface 1311, and the second side surface 1314 may be connected end to end in sequence and surround the third side surface 1315 and the fourth side surface 1316.
[0153] Therefore, the third side 1315 and the fourth side 1316 can be flat. This allows the thickness of the main unit housing 11 to be made smaller.
[0154] In some implementations, such as Figure 7 As shown, the angle between the light-emitting surface 1311 and the first side surface 1313 is α, and the angle between the light-emitting surface 1311 and the second side surface 1314 is β. The difference between α and β is less than or equal to 10°.
[0155] That is to say, the angle α between the light-emitting surface 1311 and the first side surface 1313 is approximately the same as the angle β between the light-emitting surface 1311 and the second side surface 1314. Furthermore, in the plane where the light-emitting aperture 111 is located, the orthographic projection of the light-incident surface 1312 can be set close to the orthographic projection of the light-emitting surface 1311, thereby enabling the light-incident surface 1312 to more accurately focus the incident light rays onto the light-emitting surface 1311.
[0156] The above is a brief introduction to the first light-transmitting element 131 in the embodiments of this application.
[0157] Please continue to refer to this. Figure 11 In some embodiments, the skin care device 100 further includes a light filter assembly 14, which is disposed on the side of the light emitting assembly 12 facing the light emitting hole 111. The light filter assembly 14 is used to filter the light emitted by the light emitting assembly 12 toward the light emitting hole 111.
[0158] For example, the filter assembly 14 can be located between the light-emitting assembly 12 and the first light-transmitting element 131.
[0159] Please continue to refer to this. Figure 12 In some embodiments, the surface of the main housing 11 is further provided with a mounting port 114. The filter assembly 14 includes a detachable filter 141, which is detachably mounted to the main housing 11 via the mounting port 114. Furthermore, the user can replace different types of detachable filters 141 according to actual skin care needs, so that the skin care device 100 can be used for more different types of light therapy.
[0160] Please continue to refer to this. Figure 13 In some embodiments, the light filtering assembly 14 includes at least one movable filter 142, which is movably disposed within the main housing 11. The movable filter 142 can be moved to a filtering position to filter light emitted from the light emitting assembly 12 towards the light emitting aperture 111; the movable filter 142 can also be moved to a retraction position to retract light emitted from the light emitting assembly 12 towards the light emitting aperture 111. Furthermore, the user can adjust the position of the movable filter 142 according to actual skin care needs, so that the skin care device 100 can be adapted to more different types of light therapy.
[0161] Please continue to refer to this. Figure 14 This application embodiment also provides an accessory head 200 for a skin care device 100. The skin care device 100 includes a light-emitting aperture 111, which generates light emitted from the light-emitting aperture 111 onto the skin to be treated. The accessory head 200 includes an accessory housing 21 and a second light-transmitting element 22. The accessory housing 21 is detachably connected to the skin care device 100, allowing the accessory head 200 to be detachably connected to the skin care device 100. The second light-transmitting element 22 is disposed in the accessory housing 21. When the accessory head 200 is detachably connected to the skin care device 100, the second light-transmitting element 22 focuses or diffuses the light emitted from the light-emitting aperture 111 and transmits it to the skin to be treated.
[0162] Therefore, the light emitted from the skin care device 100 can be focused or diffused through the second light-transmitting element 22, so that the skin care device 100 can meet more different care needs of users.
[0163] Taking the second light-transmitting element 22 as an example, which focuses the light emitted from the light-emitting hole 111 and transmits it to the skin to be treated, the energy intensity of the light emitted to the skin to be treated can be increased by the second light-transmitting element 22, thereby improving the skin care effect.
[0164] For example, the second light-transmitting element 22 can be a convex lens. For instance, the second light-transmitting element 22 can be a plano-convex lens, a biconvex lens, etc., and the embodiments of this application do not limit this.
[0165] In some embodiments, the structure of the second light-transmitting element 22 can refer to the specific structure of the first light-transmitting element 131, and will not be described in detail here.
[0166] Optionally, taking the second light-transmitting element 22 as an example of diffusing the light emitted from the light-emitting hole 111 and transmitting it to the skin to be treated, the second light-transmitting element 22 can enable the light generated by the skin care device 100 to be directed to a larger area of the skin to be treated, thereby improving the efficiency of skin care. Alternatively, the second light-transmitting element 22 can reduce the energy intensity of the light directed to the skin to be treated, thereby avoiding excessive local temperature of the skin to be treated, thereby improving the skin care effect.
[0167] This application also provides a skin care component, which includes a detachably connected skin care device 100 and an accessory head 200.
[0168] In some embodiments, the skin care device 100 is the skin care device 100 described above, and / or, the accessory head 200 is the accessory head 200 described above.
[0169] Therefore, when the skin care device 100 is the skin care device 100 described above, the skin care components also have all the technical effects of the skin care device 100 described above, and the embodiments of this application will not be described in detail here.
[0170] When the accessory head 200 is the accessory head 200 described above, the skin care component also has all the technical effects of the accessory head 200 described above, which will not be repeated here in the embodiments of this application.
