[0022] This embodiment relates to a skin gloss meter, such as... Figures 1-10As shown, the device includes a housing 1, a support 2, an incident optical path unit 3, a reflected optical path unit 4, and a calibration assembly 5. The housing 1 has a first sidewall 11, with a detection port 111 connecting the outside and the inside of the housing 1. The support 2 is disposed inside the housing 1 and has an incident channel 21 and a reflection channel 22 connected at an angle. The incident channel 21, the detection port 111, and the reflection channel 22 are sequentially connected. The incident optical path unit 3 is disposed inside the incident channel 21 and is used to emit a light beam toward the detection port 111. The reflection... The optical path optical unit 4 is set in the reflection channel 22 and is used to receive the light beam reflected by the object under test; the bracket 2 is configured to provide a transmission path for the light beam emitted by the incident optical path optical unit 3 and the light beam reflected by the object under test, ensuring that the incident light beam can be guided to the detection port 111 through the incident channel 21 and the reflected light beam can be received by the reflection optical path optical unit 4 through the reflection channel 22, realizing the orderly connection of the optical path. At the same time, the incident channel 21 and the reflection channel 22 provide installation space for the incident optical path optical unit 3 and the reflection optical path optical unit 4, respectively.

[0023] Specifically, during calibration, the housing 52 is installed onto the housing 1, so that the reference plate 51 covers the detection port 111. The light beam emitted by the incident light path optical unit 3 illuminates the reference plate 51. The reflected light from the reference plate 51 is received by the reflection light path optical unit 4 through the reflection channel 22. The skin gloss meter uses the reflection parameters of the reference plate 51 as the standard to calibrate the optical path system error. During testing, the housing 1 is first removed from the housing 52, and then the detection port 111 is placed against the skin surface. The light beam emitted by the incident light path optical unit 3 is reflected after illuminating the skin. The reflected light enters the reflection channel 22 of the bracket 2 through the detection port 111. The reflection light path optical unit 4 receives the reflected light and then converts the light signal into an electrical signal, which is transmitted to the control circuit board 7 for processing into gloss data. The data is then displayed on a display device, such as a screen or electronic devices like mobile phones or computers, via wired or wireless transmission.

[0024] The calibration component 5 includes a reference plate 51 and a storage base 52. The reference plate 51 is fixed to the storage base 52. The reference plate 51 can be one of a black glass plate, a ceramic plate, or a metal plate, and is preferably a black glass plate.

[0025] The storage base 52 is detachably connected to the housing 1 so that the reference plate 51 can cover or open the detection port 111. Optionally, the storage base 52 is detachably assembled to the housing 1 via a magnetic structure, a threaded structure, or a snap-fit ​​structure. Before testing, the storage base 52 can be connected to the housing 1 so that the reference plate 51 covers the detection port 111 for optical path calibration, reducing system errors. After calibration, the calibration component 5 can be removed from the housing 1 to open the detection port 111, allowing the detection port 111 to come into contact with the skin. Alternatively, when not in use, the calibration component 5 can be connected to the housing 1. The detachable design of the storage base 52 and the housing 1 facilitates the daily maintenance of the reference plate 51. At the same time, the storage base 52 can be separated in the non-calibration state to avoid obstructing the detection optical path. The storage base 52 provides storage space for the reference plate 51 and the housing 1. The reference plate 51 is directly fixed on the storage base, eliminating the need to store the reference plate 51 separately. The reference plate 51 and the housing 1 can be stored together in the storage base 52, reducing the problem of the reference plate 51 being lost due to its small size. When using the skin gloss meter, the user does not need to find the reference plate 51 from other places, simplifying the operation and improving the convenience of the user in using the skin gloss meter.

[0026] In some embodiments, such as Figure 4 , Figure 8 As shown, in Figure 8 In the diagram, the W direction represents the height direction of the skin gloss meter. The angle between the central axis of the incident channel 21 and the central axis of the reflection channel 22 is designed to be an obtuse angle, which reduces the installation height space of the bracket 2 inside the housing 1, thereby effectively reducing the storage height. Preferably, the angle between the central axes of the incident channel 21 and the reflection channel 22 is 120°±5°.

[0027] In some embodiments, such as Figures 2-9 As shown, the skin gloss meter also includes a first magnetic element 53 and a second magnetic element 12 that are magnetically attracted to each other. The first magnetic element 53 is fixed to the storage base 52, and the second magnetic element 12 is fixed to the housing 1. The housing 1 and the storage base 52 are magnetically connected through the first magnetic element 53 and the second magnetic element 12. This magnetic connection method enables quick assembly and disassembly of the storage base 52 and the housing 1, ensuring stable coverage of the detection port 111 by the reference plate 51 during calibration, and facilitating quick removal of the calibration component 5 during testing, thus improving operational convenience and structural stability. Optionally, both the first magnetic element 53 and the second magnetic element 12 are magnets. In other embodiments, one of the first magnetic element 53 and the second magnetic element 12 is a magnet, and the other is an iron sheet or iron block.

[0028] Furthermore, to ensure that the light beam emitted by the incident optical unit 3 illuminates the center of the reference plate 51 during each calibration test, thereby improving the accuracy of skin detection, at least two first magnetic suction members 53 are provided, located on opposite sides of the reference plate 51 respectively; the number of second magnetic suction members 12 corresponds one-to-one with the number of first magnetic suction members 53, and the second magnetic suction members 12 are located on opposite sides of the detection port 111 respectively. Specifically, the first magnetic suction members 53 are located in the extension direction of the long side of the reference plate 51, and the precise alignment of the reference plate 51 and the detection port 111 is achieved through the symmetrically distributed magnetic positioning structure.

[0029] In some embodiments, such as Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 9 As shown, the storage base 52 is provided with a storage groove 54 for accommodating the housing 1. The first side wall 11 is located within the storage groove 54. The housing 1 extends at least partially out of the storage groove 54 so that the user can grasp the housing 1 to remove it from the storage base 52 for skin gloss detection. The storage groove 54 includes a groove bottom 541 and a surrounding wall 543. The reference plate 51 is fixed on the groove bottom 541. The groove bottom 541 is disposed opposite to the first side wall 11. The surrounding wall 543 can guide the insertion direction of the housing 1 and limit the lateral displacement of the housing 1 within the storage groove 54, reducing the offset or shaking of the housing 1 and further improving the structural stability under calibration conditions. At the same time, the design of the surrounding wall 543 can block external light from entering the detection port 111, reducing the interference of external light on the reflected light of the reference plate 51, reducing the influence of external light on the optical parameters of the incident light path and the reflected light path, thereby improving the calibration accuracy. Optionally, the reference plate 51 can be fixed to the bottom of the tank 541 by means of adhesive, inlay, bolt structure or double-sided tape, with the bottom of the tank 541 being set opposite to the first side wall 11 to ensure the coaxiality of the reference plate 51 and the detection port 111 under the calibration state.

[0030] Furthermore, such as Figure 9 As shown, to facilitate the removal of the housing 1, the height of the storage base 54 is H1 and the height of the housing 1 is H2 along the axial direction of the storage slot 54. Preferably, the height of the enclosure 543 is designed to be 1 / 3 to 1 / 2 of the height of the shell 1, which ensures the structural stability of the shell 1 when it is inserted, and avoids excessive wrapping that would make it difficult to remove the shell 1.

[0031] In some embodiments, such as Figure 2 , Figure 8As shown, to reduce the impact of liquid at the bottom 541 of the storage tank 54 on the accuracy of calibration and testing, a boss 542 is provided on the bottom 541 of the storage tank 54. The boss 542 has an assembly groove for mounting the reference plate 51 and the first magnetic chuck 53. The thickness of the reference plate 51 and the first magnetic chuck 53 is less than or equal to the depth of the assembly groove to ensure that the surfaces are flush after installation. The side of the boss 542 opposite to the bottom 541 and the first sidewall 11 are both smooth planes to ensure a tight fit and reduce gaps.

[0032] In some embodiments, such as Figure 8 As shown, the incident light path optical unit 3 includes a light source 31, a first filter 33, and a first condenser lens 34. The light source 31, the first filter 33, the first condenser lens 34, and the detection port 111 are arranged sequentially along the axial direction of the incident channel 21. The reflected light path optical unit 4 includes a receiver 41 and a second condenser lens 43. The detection port 111, the second condenser lens 43, and the receiver 41 are arranged sequentially along the axial direction of the reflection channel 22.

[0033] It should be noted that the initial beam generated by the light source 31, after being filtered by a filter and shaped by a condenser lens, is directed at a specific angle towards the detection port 111 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 beam generated by the incident optical unit 3 is not limited. For example, the incident angle of the beam generated by the incident optical unit 3 can be 20°±5°, 60°±5°, or 85°±5°, etc. Preferably, the incident angle of the beam generated by the incident optical unit 3 is 60°±5°. The light source 31 can be a red, green, or white light lamp. Preferably, the light source 31 is a white LED, incandescent lamp, white fluorescent lamp, or white electrodeless lamp, preferably a white LED, which can provide a stable detection beam. The first filter 33 is a bandpass filter to filter stray light and ensure that the incident light wavelength is stable within the target range. The first condenser lens 34 is used to converge the diverging beam into a parallel beam or a beam at a specific angle, improving the parallelism and illumination accuracy of the incident light. Optionally, the receiver 41 is a photodiode, a photomultiplier tube, or a spectrometer; preferably, the receiver is a photodiode. The reflective optical path unit also includes a second circuit board on which the receiver is integrated.

[0034] Furthermore, such as Figure 8 As shown, the light source 31 includes a first circuit board and an LED bead disposed on the side of the first circuit board facing the detection port 111. A rubber ring 32 is disposed between the first circuit board and the first filter 33. The rubber ring 32 is sleeved on the outside of the LED bead. The first circuit board can be used to block external light from entering the incident channel 21. The rubber ring 32 is used to help fix the relative position between the LED bead and the first filter 33, reduce the optical path offset caused by the assembly gap, and further improve the directionality and purity of the incident beam.

[0035] In some embodiments, such as Figure 8 As shown, the optical unit 4 of the reflective optical path also includes a second filter 42, which allows light with a wavelength of 500nm-600nm to pass through and filters other wavelengths of light. The second filter 42 is located between the receiver 41 and the second condenser lens 43.

[0036] In some embodiments, such as Figure 8 As shown, the incident channel 21 is provided with multiple first partitions 211 with through holes. The multiple first partitions 211 are spaced apart to divide the incident channel 21 into multiple interconnected first compartments. The light source 31 and the first filter 33 are located in the same first compartment. The fact that the light source 31 and the first filter 33 are in the same compartment can ensure that the initial beam enters the filter efficiently and reduce light transmission loss. The light source 31 and the first condenser lens 34 are respectively arranged in different first compartments, which can avoid the heat of the light source 31 directly affecting the optical performance of the lens. There are at least two first compartments between the first filter 33 and the first condenser lens 34. The first partition 211 between the two first compartments forms a first aperture. The aperture of the through hole of the first aperture limits the beam aperture, further filters stray light and straightens the light path direction, ensuring that the beam incident on the first condenser lens 34 has higher parallelism and energy concentration, and improving the accuracy of gloss detection.

[0037] In some embodiments, such as Figure 8 As shown, the reflection channel 22 is provided with multiple second partitions 221 with through holes. The multiple second partitions 221 are spaced apart to divide the reflection channel 22 into multiple interconnected second compartments. The second condenser lens 43 and the receiver 41 are respectively arranged in different second compartments to avoid mutual interference between the optical elements of the second condenser lens 43 and the receiver 41, thereby improving the purity of the received signal and the detection accuracy. There are at least two second compartments between the receiver 41 and the second condenser lens 43. The second partition 221 between the two second compartments forms a second aperture. The aperture of the through hole of the second aperture limits the aperture of the reflected beam, further filtering stray light and straightening the direction of the optical path.

[0038] In some embodiments, such as Figure 8 As shown, to reduce the entry of external dust and other debris into the incident channel 21 and the reflection channel 22, a first dustproof lens 212 is provided in the first compartment adjacent to the detection port 111 in the incident channel 21, and a second dustproof lens 222 is provided in the second compartment adjacent to the detection port 111 in the reflection channel 22. In other embodiments, the detection port 111 is covered with a dustproof lens.

[0039] Furthermore, to ensure that the receiver 41 and the second filter 42 are stably positioned within the same second compartment, a planar lens 223 is provided between the second filter 42 and the second partition 221.

[0040] In some embodiments, such as Figures 4-6 As shown, the skin gloss meter also includes a display module 6 and a baffle 13. The baffle 13 is disposed inside the housing 1 and extends vertically from the first side wall 11, dividing the interior of the housing 1 into a first receiving space 112 and a second receiving space 113. The detection port 111, the bracket 2, the incident light path optical unit 3, and the reflected light path optical unit 4 are distributed in the first receiving space 112. The display module 6 is distributed in the second receiving space 113, and the display surface of the display module 6 is exposed on the outer surface of the housing 1 for displaying the data detected by the skin gloss meter. The baffle 13 is used to block the light from the display module 6 during operation, reducing the interference of the light entering the bracket 2 with the optical detection path and ensuring the accuracy of skin gloss detection.

[0041] It should be noted that, as Figures 4-9 As shown, the housing 1 also integrates a control circuit board 7 and a battery 8. The control circuit board 7 serves as the core control unit, and is electrically connected to the light source 31 of the incident light path optical unit 3, the receiver 41 of the reflected light path optical unit 4, the display module 6, and the battery 8. A control switch 9 embedded on the outside of the housing 1 is electrically connected to the control circuit board 7 and is used to trigger the start and stop of the detection process. The control switch 9 can be a touch switch or a button switch. The housing 1 also has a charging interface 10 embedded on it, which is electrically connected to the control circuit board 7 and supports power supply to the battery 8. The charging interface 10 can be one of a circular interface, a Mini USB interface, a Micro USB interface, a Lightning interface, or a Type-C interface.

[0042] In some embodiments, the control circuit board 7 may integrate a wireless communication module, which may be a Bluetooth module, a Wi-Fi module or an NFC module. The wireless communication module is used for the wireless transmission of data detected by the skin gloss analyzer and supports connection with terminal devices such as smartphones and tablets, so that users can view, store and analyze historical detection data in real time.

[0043] In some embodiments, such as Figure 2 , Figures 4-10As shown, the housing 1 includes a first outer shell 14 and a second outer shell 15, with a first sidewall 11 located on the first outer shell 14. The first outer shell 14 is provided with a first insertion portion 141, which extends along the circumferential edge of the first outer shell 14. The second outer shell 15 is provided with a second insertion portion 151 that is adapted to the first insertion portion 141, which extends along the circumferential edge of the second outer shell 15. One of the first insertion part 141 and the second insertion part 151 is a slot, and the other is an insertion strip. The insertion strip is inserted into the slot. Through the continuous insertion of the circumferential edge of the first housing 14 and the circumferential edge of the second housing 15, the gap between the first insertion part 141 and the second insertion part 151 becomes a tortuous channel similar to a "Z" or "U". If light wants to enter the housing 1 through the gap between the first insertion part 141 and the second insertion part 151, it must undergo multiple reflections and refractions in this narrow and tortuous gap, which can effectively reduce the amount of external light entering the housing 1, thereby reducing the interference of external light on optical detection.

[0044] In some embodiments, as shown in the figure Figures 4-7 As shown, to facilitate the assembly of the housing 1, the first housing 14 includes a first housing cover 142 and a second housing cover 143. The first housing cover 142 and the second housing cover 143 surround a receiving cavity. A baffle 13 is vertically disposed on the second housing 15. One edge of the first housing cover 142 is connected to one edge of the second housing cover 143. A third insertion part 1421 extends from one edge of the first housing cover 142, and a fourth insertion part 1432 extends from one edge of the second housing cover 143 and is inserted into the third insertion part 1421. In other embodiments, one edge of the first housing cover 142 and one edge of the second housing cover 143 are integrally formed or fixed by hot injection molding. The cross-section of the first housing 14 is U-shaped, and the baffle 13 and the second housing 15 are integrally formed or fixed by hot injection molding.
