[0022] This embodiment relates to a multifunctional beauty device, such as... Figures 1-3As shown, the device includes a housing 100, a stimulation unit 200, a skin gloss detection unit 300, and a display unit 400. The housing 100 has an internal cavity. The stimulation unit 200 is fixed to the housing 100 and is used to stimulate the skin for therapeutic purposes, realizing the basic beauty functions of the device. The skin gloss detection unit 300 is located within the cavity and is used to detect skin gloss data, realizing the skin gloss detection function of the device. The display unit 400 is located on the housing 100 and is used to display gloss data. The display unit 400 allows users to intuitively understand skin gloss data. By incorporating the skin gloss detection unit 300 and the display unit 400 into the housing 100, the functionality of the beauty device is enhanced. Users can understand their own skin gloss status without purchasing a separate skin analyzer, and can flexibly adjust their skincare routine based on the test results. This not only saves the cost of purchasing a skin analyzer but also reduces the space occupied by multiple devices, improving the convenience and practicality of using the beauty device and enhancing the user experience.

[0023] In some embodiments, such as Figure 5 , Figures 7-9 As shown, to enable the multifunctional beauty instrument to detect skin glossiness, the outer shell 100 has a detection surface 10 that contacts the target skin, and a detection port 12 communicating with the receiving cavity is provided on the detection surface 10; the skin glossiness detection unit 300 includes an incident light path optical unit 30, a reflected light path optical unit 31, and a light path support 32. The light path support 32 is fixed to the outer shell 100, and the light path support 32 has an incident light path channel 320, a light-passing hole 322, and a reflected light path channel 323. The incident light path channel 320, the light-passing hole 322, and the reflected light path channel 323 are connected in sequence. The light-passing hole 322 and the detection port 12 are arranged opposite each other and form a continuous light path channel. The incident light path optical unit 30 is disposed in the incident light path channel 320 and is used to emit a light beam toward the detection port 12; the reflected light path optical unit 31 is disposed in the reflected light path channel 323 and is used to receive the light beam reflected by the object being detected.

[0024] During testing, the detection port 12 is placed against the surface of the target object (such as skin, calibration plate 500, etc.). The light beam emitted by the incident light path optical unit 30 shines on the object along the incident light path channel 320 and is reflected. The reflected light enters the reflection channel of the light path support 32 through the detection port 12. The reflected light path optical unit 31 receives the reflected light, and the receiver 310 of the reflected light path optical unit 31 converts the light signal into an electrical signal, which is transmitted to the control circuit board of the beauty instrument for processing into gloss data. Then, the gloss data is displayed through the display unit 400.

[0025] In some embodiments, such as Figure 6 , Figures 7-9 As shown, the beauty device also includes a calibration plate 500 that is detachably mounted on the housing 100. The calibration plate 500 is used to cover or open the detection port 12. The calibration plate 500 can be selected from one of a black glass plate, a ceramic plate, or a metal plate, preferably a black glass plate. The calibration plate 500 can be detachably mounted on the housing 100 through a magnetic or snap-fit ​​structure. Specifically, before testing, the calibration plate 500 can be connected to the housing to cover the detection port 12 for optical path calibration, reducing system errors. After calibration, the calibration plate 500 can be removed from the housing 100 to open the detection port 12, allowing it to come into contact with the skin. When not in use, the calibration plate 500 can be connected to the housing. The calibration plate 500 is designed to be detachably assembled with the housing 100, serving both as a protective cover for the detection port 12 to reduce dust entry and forming an integrated storage structure with the housing 100. This effectively solves the problem of traditional sheet-shaped calibration plates being easily lost when stored separately. When using the skin gloss meter, users no longer need to search for the calibration plate 500 elsewhere, simplifying the calibration process and improving convenience.

[0026] Specifically, during calibration, the calibration plate 500 is installed on the housing 100 so that the calibration plate 500 covers the detection port 12. The light beam emitted by the incident light path optical unit 30 illuminates the calibration plate 500. The reflected light beam after passing through the calibration plate 500 is received by the reflected light path optical unit 31 through the reflected light path channel 323. The beauty instrument uses the reflection parameters of the calibration plate 500 as the standard to calibrate the optical path system error of the skin gloss detection unit 300.

[0027] In some embodiments, such as Figures 1-6 As shown, to protect the calibration plate 500 and prevent it from being exposed and scratched, while also serving to store the calibration plate 500, the gloss meter also includes a cover plate 600. The cover plate 600 is fixed to the side of the calibration plate 500 opposite to the detection port 12. The cover plate 600 is detachably assembled with the outer shell 100, allowing the calibration plate 500 to be detachably assembled with the outer shell 100 via the cover plate 600. The cover plate 600 can be detachably assembled with the outer shell 100 via a magnetic structure, a threaded structure, or a snap-fit ​​structure. The detachable design of the storage base and the outer shell 100 facilitates the daily maintenance of the calibration plate 500. At the same time, the cover 600 can be separated in the non-calibration state to avoid obstructing the detection light path. The cover 600 also provides storage space for the calibration plate 500, which is directly fixed on the storage base. There is no need to store the calibration plate 500 separately, reducing the problem of the small size of the calibration plate 500 being lost. When using the beauty instrument to detect skin glossiness, users do not need to find the calibration plate 500 from other places, simplifying the operation and improving the convenience of users to perform skin glossiness detection.

[0028] In some embodiments, such as Figure 6 As shown, the gloss meter also includes a first magnetic chuck 601 and a second magnetic chuck 11 that are magnetically attracted to each other. The first magnetic chuck 601 is fixed to the calibration plate 500, and the second magnetic chuck 11 is fixed to the outer shell 100. The outer shell 100 and the calibration plate 500 are magnetically connected through the first magnetic chuck 601 and the second magnetic chuck 11. Alternatively, the first magnetic chuck 601 is fixed to the cover plate 600, and the second magnetic chuck 11 is fixed to the outer shell 100. This magnetic connection method enables the calibration plate 500 to be quickly attached and detached from the outer shell 100, either directly or indirectly. This ensures that the calibration plate 500 stably covers the detection port 12 during calibration and facilitates the quick removal of the calibration plate 500 during testing, improving operational convenience and structural stability. Optionally, both the first magnetic chuck 601 and the second magnetic chuck 11 are magnets. In other embodiments, one of the first magnetic chuck 601 and the second magnetic chuck 11 is a magnet, and the other is an iron sheet or iron block.

[0029] In some embodiments, such as Figure 2 , Figure 3 , Figure 10 As shown, the housing 100 includes a second sidewall 19 and a boss 13 fixed to the second sidewall 19. The boss 13 protrudes outward from the second sidewall 19, and the detection port 12 is opened on the boss 13. The cover plate 600 has a mounting groove for accommodating the boss 13. The cover plate 600 covers the boss 13 and is in close contact with the second sidewall 19. The boss 13 and the calibration plate 500 are located in the mounting groove. Through the close fit between the cover plate 600 and the second sidewall 19, an L-shaped or Z-shaped tortuous gap structure is formed between the cover plate 600 and the housing 100. If external light is to enter the mounting groove through this gap, it needs to undergo multiple reflections and refractions in the narrow and tortuous channel, which can significantly reduce the incident intensity of external ambient light and thus effectively reduce the interference of external stray light on the optical detection accuracy.

[0030] In some embodiments, such as Figure 10 As shown, the cover plate 600 includes a bottom wall 602 and a surrounding wall 604. The surrounding wall 604 is fixed to the edge of the bottom wall 602, and the bottom wall 602 and the surrounding wall 604 together form an installation groove. The bottom wall 602 is provided with a receiving groove opposite to the detection port 12, and the calibration plate 500 is fixed in the receiving groove. Along the axial direction of the detection port 12, the height of the calibration plate 500 is less than the depth of the receiving groove. This structural design can prevent the calibration plate 500 from protruding from the surface of the receiving groove and effectively prevent the calibration plate 500 from being scratched and damaged during use.

[0031] In some embodiments, the surface of the receiving groove is in direct contact with the detection surface 10 on the boss 13. This contact design ensures the continuity of the optical path and reduces the reflection loss of light during propagation. At the same time, the way in which the outer surface of the receiving groove is in contact with the detection surface 10 can block external ambient light interference and ensure the stability and accuracy of the optical path transmission between the calibration plate 500 and the skin gloss detection unit 300.

[0032] In some embodiments, such as Figure 2 , Figure 3 , Figure 10 As shown, the display unit 400 is fixed to the boss 13, with at least a portion of the display unit 400 protruding from the boss 13. The cover plate 600 is spaced apart from the display unit 400, creating a gap between the cover plate 600 and the display surface of the display unit 400. This gap design prevents scratches caused by direct contact between the cover plate 600 and the display surface. The portion of the display unit 400 protruding from the boss 13 is covered by the cover plate 600, reducing dust accumulation and keeping the display surface clean. Simultaneously, since the cover plate 600 covers the boss 13 of the housing, a physical gap is formed between the cover plate 600 and the exposed display unit 400. This gap design increases the resistance of the electrostatic conduction path between the cover plate 600 and the display unit 400, reducing electrostatic transfer caused by close contact, induction, or contact friction between the cover plate 600 and the display unit 400. This reduces interference from static electricity on the electronic components of the display unit 400, ensuring stable display of gloss data by the display unit 400.

[0033] In some embodiments, such as Figure 5 , Figure 6 , Figure 10 As shown, the display unit 400 includes a display screen 401 and a fourth circuit board 402 electrically connected to the display screen 401. The display screen 401 can be an LCD display screen, an OLED display screen, or a TFT-LED display screen. Specifically, to facilitate the assembly of the display unit 400, the outer surface of the optical path bracket 32 ​​is provided with a mounting position for mounting the display screen 401. The mounting position cooperates with the structure of the inner sidewall of the housing 100 to clamp and fix the display screen 401. The outer surface of the optical path bracket 32 ​​is also provided with a insertion slot for inserting and fixing the fourth circuit board 402.

[0034] like Figure 5 , Figure 6As shown, to further ensure that the light beam emitted by the incident optical unit 30 illuminates the center of the calibration plate 500 during each calibration test, thereby improving the accuracy of skin detection, multiple first magnetic suction elements 601 are symmetrically arranged on opposite sides of the calibration plate 500. The number of second magnetic suction elements 11 corresponds one-to-one with the first magnetic suction elements 601, and the second magnetic suction elements 11 are located on opposite sides of the detection port 12. Specifically, the symmetrically distributed magnetic positioning structure achieves precise alignment between the calibration plate 500 and the detection port 12, ensuring that during calibration, the light beam emitted by the incident optical unit 30 illuminates the same position on the calibration plate 500 each time, further ensuring the accuracy of skin detection.

[0035] In some embodiments, such as Figure 7 , Figure 8 As shown, to realize the function of detecting skin glossiness by reflecting light, the incident light path optical unit 30 includes a light source 301, a first filter 305, and a first condenser lens 306. The light source 301, the first filter 305, the first condenser lens 306, and the light-passing aperture 322 are arranged sequentially along the axial direction of the incident light path channel 320. The reflected light path optical unit 31 includes a receiver 310 and a second condenser lens 312. The light-passing aperture 322, the second condenser lens 312, and the receiver 310 are arranged sequentially along the axial direction of the reflected light path channel 323.

[0036] It should be noted that the initial light beam generated by the light source 301, after being filtered by a filter and shaped by a condenser lens, is directed at a specific angle towards the light aperture 322, the detection port 12, and the surface of the object to be measured, thus realizing the optical path input for gloss detection. In this embodiment, the incident angle of the light beam generated by the incident optical path unit 30 is not limited. For example, the incident angle of the light beam generated by the incident optical path unit can be 20°±5°, 60°±5°, or 85°±5°, etc. Preferably, the incident angle of the light beam generated by the incident optical path unit is 60°±5°. The light source 301 can be a red, green, or white light LED. The light source 301 can be a white LED, incandescent lamp, white fluorescent lamp or white electrodeless lamp, preferably a white LED bead, which can provide a stable detection beam; the first filter 305 is a bandpass filter to filter stray light to ensure that the wavelength of the incident light is stable within the target range; the first condenser lens 306 is used to converge the diverging beam into a parallel beam or a beam at a specific angle, thereby improving the parallelism and illumination accuracy of the incident light.

[0037] Furthermore, such as Figure 8As shown, the incident light path optical unit 30 also includes a rubber ring 304, which is disposed between the first filter 305 and the light source 301. The two sides of the rubber ring 304 abut against the first filter 305 and the light source 301, respectively. The light source 301 includes a second circuit board 302 and an LED bead 303 disposed on the side of the second circuit board 302 facing the detection port 12. The rubber ring 304 is sleeved on the LED bead 303. The second circuit board 302 can be used to block external light from entering the incident channel, and the rubber ring 304 is used to help fix the relative position between the LED bead 303 and the first filter 305, reduce the light path offset caused by assembly gaps, and further improve the directionality of the incident beam. The reflective optical path unit 31 further includes a second filter 311, which is disposed between the receiver 310 and the second condenser lens 312. The second filter 311 allows light with a wavelength of 500nm-600nm to pass through while filtering other wavelengths, so that the receiver 310 receives visible light with a wavelength of 500nm-600nm. The receiver 310 is a photodiode, a photomultiplier tube, or a spectrometer; preferably, the receiver 310 is a photodiode. The reflective optical path unit 31 also includes a third circuit board 314 disposed within the reflective optical path channel 323 and located on one side of the receiver 310. The receiver 310 is integrated on the third circuit board 314. The third circuit board 314 provides a carrying space for the receiver 310 while further blocking external light from entering the reflective optical path channel 323, thereby reducing the impact of external light on the accuracy of gloss detection.

[0038] In some embodiments, such as Figure 8 As shown, the incident light path channel 320 is provided with multiple first partitions 321 with through holes. The multiple first partitions 321 are spaced apart to divide the incident light path channel 320 into multiple interconnected first compartments. The light source 301, the rubber ring 304, and the first filter 305 are located in the same first compartment, while the first condensing lens 306 and the light source 301 are arranged in different first compartments. The fact that the light source 301, the rubber ring 304, and the first filter 305 are in the same compartment ensures that the initial light beam enters the filter efficiently, reducing light transmission loss. The fact that the light source 301 and the first condensing lens 306 are arranged in different first compartments reduces the impact of the heat from the light source 301 on the optical performance of the lens. At the same time, the design of the rubber ring 304 ensures that the light source 301 and the first filter 305 are stably confined in the same compartment, reducing the displacement of the light source 301 and the first filter 305.

[0039] In some embodiments, such as Figure 8As shown, at least two first compartments are spaced between the first filter 305 and the first condenser lens 306. A first partition 321 between the two first compartments forms a first aperture. The aperture of the first aperture restricts the beam diameter, further filtering stray light and straightening the optical path direction, ensuring that the beam incident on the first condenser lens 306 has higher parallelism and energy concentration, thus improving the accuracy of gloss detection.

[0040] In some embodiments, such as Figure 8 As shown, the reflected light path channel 323 is provided with multiple second partitions 324 with through holes. The multiple second partitions 324 are spaced apart to divide the reflected light path channel 323 into multiple interconnected second compartments. The second condenser lens 312 and the receiver 310 are respectively arranged in different second compartments to avoid mutual interference between the optical elements of the second condenser lens 312 and the receiver 310, thereby improving the purity of the received signal and the detection accuracy. The receiver 310 and the second filter 311 are located in the same second compartment. To ensure that the second filter 311 and the receiver 310 are stably fixed and limited in the same second compartment, a plane lens 313 is provided between the second filter 311 and the second partition 324.

[0041] Specifically, there are at least two second compartments between the second filter 311 and the second condenser lens 312. The partition between the two second compartments forms a second aperture, which limits the aperture of the reflected light beam by limiting the aperture of the reflected light beam, further filtering stray light and straightening the direction of the light path.

[0042] In some embodiments, such as Figure 8 As shown, to reduce the entry of external dust and other debris into the incident light path channel 320 and the reflected light path channel 323, a first dustproof lens 325 is provided in the first compartment adjacent to the detection port 12 in the incident light path channel 320, and a second dustproof lens 326 is provided in the second compartment adjacent to the detection port 12 in the reflected light path channel 323. In other embodiments, the detection port 12 is covered with a dustproof lens.

[0043] In some embodiments, the incident light path channel 320 and the reflected light path channel 323 are arranged at an angle. Figure 7The W-direction is the width direction. The angle between the incident light path channel 320 and the reflected light path channel 323 is set to an obtuse angle, which can reduce the width direction of the light path support 32 installed inside the housing 100. Specifically, the angle between the central axis of the incident light path channel 320 and the central axis of the reflected light path channel 323 is 115°-125°. By setting the incident light path channel 320 and the reflected light path channel 323 to an obtuse angle of 115°-125°, the installation size of the light path support 32 in the width direction of the housing 100 is effectively reduced, the internal space layout is optimized, and the overall structure of the beauty device is more compact.

[0044] In some embodiments, such as Figure 1 , Figure 2 , Figures 4-6 As shown, the outer casing 100 includes a handle casing 17 and a functional head casing 18 disposed at one end of the handle casing 17. The functional head casing 18 includes a first mounting portion 181 and a second mounting portion 182. The first mounting portion 181 and the second mounting portion 182 are connected at an angle. A smooth arc-shaped transition surface 183 is provided at the angle between the first mounting portion 181 and the second mounting portion 182. Users can use the arc-shaped transition surface 183 to fit against the jawline of the face for physical scraping, further increasing the functionality of the beauty device. The incident light path channel 320 is located inside the first mounting portion 181, and a portion of the reflected light path channel 323 is located inside the first mounting portion 181, while another portion is located inside the handle casing 17; or, the reflected light path channel 323 is located inside the first mounting portion 181, and a portion of the incident light path channel 320 is located inside the first mounting portion 181, while another portion is located inside the handle casing 17.

[0045] In this embodiment, the angled design of the functional head housing 18 enables the separate arrangement of the skin gloss detection unit 300 and the physiotherapy unit, reducing mutual interference between the functional units.

The first circuit board 201 covers the side of the light-transmitting area 141 near the phototherapy lamp 202 to block the light generated by the phototherapy lamp 202 during operation or the light entering the skin gloss detection unit 300 through the light-transmitting area 141, thereby reducing the optical interference of external light or the physiotherapy unit on the skin gloss detection unit 300. Optionally, the phototherapy lamp panel 20 can emit one or more wavelengths of light selected from 415nm blue light, 630nm red light, 850nm near-infrared light, 560nm green light, 610nm orange light, and 290nm-400nm ultraviolet light. The phototherapy lamp 202 can be one or more selected from LEDs, lasers, fluorescent beads, halogen lamps, electrodeless lamps, and xenon arc lamps, preferably LEDs and / or lasers. This allows the beauty device to simultaneously perform phototherapy and skin radiance detection functions, enabling users to adjust their phototherapy or skincare regimens based on the detected radiance data.

[0048] In some embodiments, such as Figures 7-9 As shown, the first mounting part 181 has a first accommodating space, the detection port 12 is opened on the side of the first mounting part 181 away from the second mounting part 182, at least part of the skin gloss detection unit 300 is disposed in the first accommodating space, the second sidewall 19 is located on the side of the second mounting part 182 away from the first mounting part 181, the second mounting part 182 has a second accommodating space, the phototherapy component lamp plate is disposed in the second accommodating space, by the phototherapy lamp plate 20 and the skin gloss detection unit 300 are respectively located in different accommodating spaces, the light interference and heat impact of the phototherapy lamp plate 20 on the skin gloss detection unit 300 are reduced, the light emitted by the lamp beads on the phototherapy lamp plate is reduced from interfering with the detection light path, and the impact of temperature fluctuations on the performance of optical components is reduced, thereby improving the accuracy and stability of skin gloss detection data.

This cooling element can be a semiconductor cooling element embedded in the receiving cavity and in contact with the heat-conducting element 23. Optionally, the heating element 22 can be replaced with a radio frequency electrode.

[0051] In some embodiments, such as Figures 4-6 As shown, the housing 100 includes a first housing 15 and a second housing 16, which are mechanically connected. For example, the first housing 15 and the second housing 16 can be fixed by fasteners such as snap-fit ​​structures or screws. The stimulation unit 200 includes a vibrating element 24, which is fixed to the first housing 15. The skin gloss detection unit 300 is fixed to the second housing 16. The mechanical connection between the first housing 15 and the second housing 16 creates a discontinuous interface of mechanical impedance, which can effectively reduce the transmission of vibration from the first housing 15 to the second housing 16 and reduce the vibration interference generated by the vibrating element 24 during operation, thus reducing the impact on the stability of the optical elements of the detection unit. Optionally, the vibrating element 24 can be fixed to the inner wall of the first housing 15 by means of adhesive bonding, screw bonding, welding, etc.

[0052] In some embodiments, such as Figure 6 , Figure 10 As shown, a limiting part 161 protrudes from the inner wall of the first accommodating space of the second outer shell 16. Two limiting parts 161 are provided, located on either side of the detection port 12. The two limiting parts 161 surround a positioning groove for confining the optical path support 32 within it. The positioning groove facilitates quick alignment and installation of the optical path support 32, ensuring the coaxiality of the light-passing hole 322 and the detection hole, thereby reducing deviations in gloss detection caused by assembly errors. To ensure the optical path support 32 is stably fixed within the outer shell 100, it is secured to the second outer shell 16 using fasteners such as clips or screws.

Specifically, part of the control circuit board is located inside the functional head housing 18, and another part is located inside the handle housing 17. The control circuit board is fixed inside the housing 100 by screws. A battery 702 bracket 171 is provided inside the handle housing 17, and the battery 702 is limited within the battery 702 bracket 171.
