[0024] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative in nature and not to limit the present invention.

If the descriptions of the positions of these elements change, the indications of these directions will also change accordingly.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0027] The skin detection devices integrated into existing home beauty devices are not effective. They are easily interfered by ambient light, and the difference in light brightness will affect the accuracy of the detection results, resulting in users being unable to accurately understand their own skin condition.

[0028] See also Figures 1 to 4 This embodiment provides a skin detection device 100 , which includes a main body 10 , a camera 20 and a fill light source 30 .

[0029] Camera 20 is mounted on main body 10 and is used to capture images of a user's skin. A fill light source 30 is mounted on main body 10 and is positioned on the same side as camera 20. Fill light source 30 is capable of emitting fill light of a specific wavelength band, enabling camera 20 to capture images of the user's skin under the fill light, thereby generating data reflecting the user's skin condition.

[0030] The main body 10 is the core structure of the skin detection device 100, supporting functional modules such as the camera 20 and the fill light source 30. The main body 10 can be shaped like a cylinder, an ellipse, or a rectangular parallelepiped, as long as it is convenient for the user to hold or place on a platform for fixed use. The camera 20 is mounted on the main body 10 and is responsible for capturing images of the user's skin. Depending on the actual use case, the camera 20 can be configured as a telephoto camera 20, a short-focus camera 20, or a camera 20 with adjustable magnification, ensuring high-resolution skin images.

[0031] The fill light source 30 and the camera 20 are set on the same side of the main body 10, so that the fill light source 30 can emit standard fill light of a preset band, such as: broadband white light close to natural light or light of other specific bands, which is used to enhance the display effect of skin details and reduce ambient light interference, thereby providing a stable and uniform fill light effect for the camera 20, effectively avoiding the interference of ambient light on the skin detection results, and improving the accuracy of skin condition detection.

[0032] See also Figure 1 and Figure 2 In some embodiments, the main body 10 includes a grip portion 11 and a lampshade 12. The grip portion 11 is for a user to hold. The lampshade 12 is disposed at one end of the grip portion 11. A reflective cavity 121 with an open end is defined within the lampshade 12. The sidewalls of the reflective cavity 121 of the lampshade 12 are reflective surfaces. The camera 20 and the fill light source 30 are disposed on the bottom wall of the reflective cavity 121 of the lampshade 12.

[0033] Specifically, the grip portion 11 can be a cylindrical structure, which can provide a comfortable gripping experience for the user. A lampshade 12 is provided on the top of the grip portion 11, and a reflective cavity 121 is provided inside the lampshade 12. The diameter of the reflective cavity 121 gradually increases in the direction toward the opening to form a horn-shaped cavity. The camera 20 and the fill light source 30 are arranged on the bottom wall of the lampshade 12. The fill light emitted by the fill light source 30 is reflected by the reflective surface of the lampshade 12 and then emitted, so that most of the fill light can be effectively concentrated on the user's skin surface.

[0034] Furthermore, the bottom wall of the lampshade 12 is positioned a certain distance from its opening, allowing the open end of the lampshade 12 to be perfectly aligned with the desired skin area for testing. At this point, natural light from the external environment is completely blocked by the lampshade 12, preventing it from entering the reflective cavity 121 of the lampshade 12 and preventing it from affecting or interfering with the user's skin image. This further reduces the impact of ambient light on the testing process, significantly improving the clarity and color reproduction of the images captured by the camera 20.

[0035] See also Figure 1 and Figure 2 In some embodiments, the fill light source 30 includes a plurality of lamp beads, which are spaced around the periphery of the camera 20. The lamp beads may include cool white LEDs and / or warm white LEDs.

[0036] Among them, multiple lamp beads emit one of ultraviolet light, infrared light, blue light, red light, green light or yellow light or any combination thereof.

[0037] Specifically, the multiple lamps of the fill light source 30 can be LEDs and / or other suitable light source elements, such as thermal radiation lamps. When the user activates the skin detection device 100, the multiple lamps within the reflective cavity 121 illuminate synchronously. The light emitted by the lamps is first reflected by the reflective surface of the inner wall of the reflective cavity 121 before converging and illuminating the user's skin through the light outlet of the lampshade 12. Because the lamps are spaced around the periphery of the camera 20, light can be evenly illuminated from multiple angles on the skin surface, preventing light from being concentrated in a specific direction or area. This ensures that the overall light distribution of the skin image captured by the camera 20 is balanced.

[0038] In addition, the combined use of multiple lamp beads can also provide a flexible light source adjustment function. By controlling the brightness or switch state of each lamp bead, the user can select different lighting modes according to the detection needs. For example, all the lamp beads can be turned on for high-brightness fill light, which is suitable for skin texture or detail detection; or only some of the lamp beads can be turned on to reduce the light intensity, which is suitable for color or skin color uniformity detection to meet the detection needs of different skin conditions. As another example, the multiple lamp beads of the fill light source 30 can include cold white LEDs and warm white LEDs, which can be used to provide light of different color temperatures projected onto the skin surface to obtain skin images at different color temperatures, and can further obtain more dimensional skin analysis results by comparing skin images at different color temperatures.

[0039] In another example, the multiple lamp beads of the fill light source 30 may also emit ultraviolet, infrared, blue, red, green, yellow or other colored lights, or the multiple lamp beads may be a combination of mixed-color lamp beads.

[0040] As another example, the camera 20 can be a camera with adjustable magnification. At different magnifications, by cooperating with different forms of fill light sources 30, it can magnify and image local parts of the skin to highlight certain problem skin, making the skin detection results more intuitive and comprehensive.

[0041] See also Figure 1 and Figure 4 In some embodiments, a first rotating portion 113 is provided at one end of the grip 11, and a second rotating portion 122 is provided at the rear side of the lampshade 12. The first rotating portion 113 and the second rotating portion 122 are rotatably connected to each other, so that the lampshade 12, and the camera 20 and fill light source 30 therein, can rotate relative to the grip 11.

[0042] Specifically, the top surface of the gripping portion 11 can be set as an arcuate surface, and the first rotating portion 113 is two annular bases spaced apart from each other and arranged on the arcuate surface, and corresponding through holes are provided in the centers of the two annular bases.

[0043] The second rotating portion 122 may include a rotating column 1221 and a connecting column 1222 that are perpendicular to each other. The rotating column 1221 and the connecting column 1222 are connected to each other to form a T-shaped structure. The rotating column 1221 is located between the two annular first rotating portions 113 and is rotatably connected to the perforation of the first rotating portion 113, allowing the rotating column 1221 to rotate about its own axis. One end of the connecting column 1222 is fixedly connected to the rotating column 1221, and the other end of the connecting column 1222 is fixedly connected to the back side of the lampshade 12, so that when the rotating column 1221 rotates about its own axis, it can drive the lampshade 12 on the connecting column 1222 to pitch and rotate.

[0044] The user can adjust the angle between the lampshade 12 and the grip 11 so that the camera 20 and the fill light source 30 in the lampshade 12 can be accurately aligned with the skin area to be detected. For example, when detecting different parts of the body such as the face, arms, and legs, the user does not need to move the wrist or arm too much, and can adjust the angle directly by rotating the lampshade 12 of the device, thereby improving the convenience and comfort of use.

[0045] For example, when a user places the lampshade 12 against the skin and needs to move it from the facial skin to the neck skin, the user can hold the grip portion 11 and move it downward. At this time, the light outlet end surface of the lampshade 12 is always in contact with the user's skin, and the angle between the lampshade 12 and the grip portion 11 can change according to the user's skin contour, so that the lampshade 12 can always be in contact with the user's skin.

[0046] In some embodiments, an elastic damping ring may be disposed between the first rotating portion 113 and the second rotating portion 122, located at the junction of the two rotating portions. This elastic damping ring increases friction between the first rotating portion 113 and the second rotating portion 122, preventing the lampshade 12 from rotating too quickly or too loosely. When the user rotates the lampshade 12, the damping ring provides moderate resistance, allowing the user to flexibly adjust the device angle according to testing requirements and secure it in place to ensure controllable angle.

[0047] See also Figure 1 and Figure 2 In some embodiments, the grip portion 11 includes a first rod 111 and a second rod 112. The first rod 111 defines a mounting cavity with an open bottom. The second rod 112 is connected to the mounting cavity of the first rod 111 and is slidably connected to the inner wall of the first rod 111, allowing the second rod 112 to extend or retract into the first rod 111.

[0048] Specifically, the grip 11 can be composed of two slidably connected sections, a first rod 111 and a second rod 112. The second rod 112 is mounted within the mounting cavity of the first rod 111, allowing it to slide along the inner wall of the first rod 111 for flexible length adjustment. When extended, the second rod 112 provides a longer grip 11, facilitating tests requiring a wider operating range. When retracted, the device becomes more compact, making it easier to carry and store.

[0049] In some embodiments, a vertically extending friction band 1121 is further provided on the outer wall of the second rod 112. Correspondingly, an elastic member 1111 is provided on the inner wall of the first rod 111, corresponding to the friction band 1121. When the first and second rods 111, 112 slide against each other, the elastic member 1111 can slide against the friction band 1121, providing appropriate friction, ensuring a certain degree of damping when the user adjusts the length of the grip 11, and preventing the second rod 112 from sliding due to external forces during operation.

[0050] See also Figure 4 In some embodiments, a controller 16 is provided within the main body 10. The controller 16 is electrically connected to the camera 20 and the fill light source 30. The controller 16 can control the fill light source 30 to emit fill light of a specific wavelength band. The camera 20 can transmit the captured user image information to the controller 16 for analysis and processing.

[0051] Specifically, controller 16 is the core control unit of skin detection device 100, integrated on a circuit board within grip 11. It flexibly controls fill light source 30 to emit fill light of a specific wavelength band based on user commands or pre-set programs. It also analyzes skin images captured by camera 20 to obtain specific user skin data. This data allows the beauty device to select different beauty modes to suit the user's individual needs.

[0052] In some embodiments, the controller 16 may include a data processing module. The data processing module is electrically connected to the camera 20 and is capable of receiving images of the user's skin captured by the camera 20 and directly analyzing and processing the images to obtain data reflecting the user's skin condition. The user can use this data processing result to adjust the mode of a device such as a beauty instrument to achieve better beauty results.

[0053] In some embodiments, the controller 16 may include a light control module. A control button 13 is provided on the main body 10 and is electrically connected to the light control module of the controller 16. A user presses the control button 13 to output a control signal, which in turn changes the fill light state emitted by the fill light source 30.

[0054] Specifically, the control button 13 may be provided on the outer wall of the first rod 111 , so that the user can press the control button 13 regardless of whether the grip portion 11 is in the telescopic state or the extended state.

[0055] When using the device, the user can send a control signal to the device by pressing the control button 13. Different control signals can be triggered by pressing the button once, twice, or for a long time. When the light control module in the controller 16 receives the control signal, it can adjust the fill light source 30 according to a preset computer program.

[0056] For example, a single press of the control button 13 can switch the wavelength or brightness mode of the fill light, while a long press can turn off the fill light source 30. Furthermore, when detecting skin color, the user can use the control button 13 to adjust the fill light source 30 to a softer white light, while when detecting skin spots, the fill light source 30 can be selected to emit a stronger blue light. Users can easily switch the device's fill light source 30 mode and select the appropriate lighting conditions, thereby improving the accuracy of skin detection.

[0057] In some embodiments, the controller 16 may further include a wireless transmission module for communicating with an external terminal device via a signal, so that the wireless transmission module can transmit the analysis results of the data processing module or the skin image captured by the camera 20 to the external terminal device.

[0058] The external terminal device can be a mobile phone, tablet, computer, or backend cloud, and the wireless transmission module can communicate with it via wireless communication technologies such as Wi-Fi, Bluetooth, and NFC. The external terminal device can run an application (app) compatible with the skin detection device 100, which can receive the analysis and processing results sent by the wireless transmission module and display them intuitively on the user interface. Users can view and manage the test results through the terminal device and adjust subsequent beauty care plans based on changes in the data.

[0059] Of course, in some other embodiments, the skin image taken by the camera 20 can also be directly transmitted to the terminal device, and the skin image can be analyzed and processed by a computing program in the terminal device to obtain the user's skin data, and the beauty mode of the beauty instrument can be adjusted according to the skin data.

[0060] In some embodiments, the skin detection device 100 can also be directly connected to the beauty device via a wireless transmission module. After its data processing module analyzes and processes the user's skin data, it directly transmits the skin data to the beauty device, which automatically switches to the corresponding beauty mode to meet the user's personalized beauty needs.

[0061] See also Figure 4 In some embodiments, the main body 10 further includes a built-in battery 14. The built-in battery 14 is electrically connected to the camera 20 and the fill light source 30 through the controller 16 to supply power to the controller 16, the camera 20 and the fill light source 30.

[0062] The internal battery 14 can be located within the second rod 112 and can provide stable power to the controller 16, camera 20, and fill light source 30, ensuring continuous operation and stable performance of the device. This also frees the skin detection device 100 from external power constraints during use, ensuring high portability and battery life, further enhancing the user experience.

[0063] See also Figure 1 In some embodiments, the main body 10 further includes a charging port 15 . The charging port 15 is disposed at the bottom of the main body 10 and is electrically connected to the built-in battery 14 . The charging port 15 is used to connect to an external power source to supply power to the built-in battery 14 .

[0064] Specifically, the charging port 15 can be a standard USB port or Type-C for greater compatibility. The charging port 15 can be located at the bottom of the second rod 112 so that the charging port 15 is not blocked by the first rod 111 when the grip 11 is retracted.

[0065] In summary, this embodiment provides a skin detection device 100 comprising a main body 10, a camera 20, and a fill light source 30. The fill light source 30 can emit standard light of a preset wavelength band to supplement the camera 20's image capture, thereby providing stable and uniform fill light for the camera 20. This effectively prevents ambient light from interfering with the skin detection results and improves the accuracy of skin condition detection. This enables the skin detection device 100 to adapt to different usage environments to ensure consistent detection results, allowing users to perform skin care at home with professional-grade detection results, thereby enhancing the beauty effects of the beauty device.
