Description

Technical Field

[0001] This application relates to the field of skin analyzers, and in particular to a filter switching lens mount. Background Technology

[0002] Currently, common skin testing devices mainly use RGB light, polarized light, or UV ultraviolet light to irradiate and image the skin. They are complex in structure, bulky in size, and have high requirements for ambient light. Some even require a black box to meet the requirement of testing in a dark environment. Therefore, they are expensive and cannot be used for home testing. To understand the condition of facial skin, one must go to a specific institution for testing, which is time-consuming, laborious, and expensive.

[0003] To address the aforementioned technical deficiencies, publication number (CN202322912617.8) discloses a hyperspectral skin detector, comprising a detection component, the detection component including a hyperspectral camera; a detection position alignment component with a display window for calibrating the detection area, the detection position alignment component coinciding with the vertical central axis of the detection component; a control component electrically connected to the detection component and the detection position alignment component; and a housing for accommodating the detection component and the detection position alignment component, the front of the housing having a light inlet for the detection component and a display window for the detection position alignment component. By using a hyperspectral camera as the detection component of the skin detector, and aligning the central axes of the detection component and the detection position alignment component, the size of the skin detector is reduced.

[0004] During use, unstable lighting conditions at the application site can interfere with the lens used for skin scanning, causing high reflectivity and affecting the stability of the detection. The existing solution is to install a filter on top of the lens to filter the light and prevent high reflectivity. However, since the lens is installed inside the detector and the detector housing is made of snap-fit, installing a filter would be difficult.

[0005] Therefore, a lens mount that facilitates filter switching needs to be designed. Utility Model Content

[0006] To address the difficulty of switching filters, this application provides a filter switching lens mount.

[0007] This application provides a filter switching lens mount, which is disposed inside a skin detector; the technical solution is as follows: it includes: a skin detector body, including a shell and a mounting groove for mounting the lens mount defined by the shell;

[0008] The lens has two lenses for scanning the skin;

[0009] A support, installed in a mounting slot, to support two lenses;

[0010] A light-diffusing plate is located above the lens.

[0011] A light filter is placed between the lens and the light-diffusing plate;

[0012] The main body has at least one slot on its outer wall that leads into the mounting groove; the two lenses are a hyperspectral lens and an RGB lens, respectively; the support is located at the bottom of the mounting groove and is integrally formed with the outer shell; the light-diffusing plate is detachably set at the slot.

[0013] Optionally, a light-diffusing plate, a PCBA board, light-blocking cotton, a filter, and a lens are arranged sequentially along the first direction within the mounting slot.

[0014] Optionally, a sliding block is set to move the inner wall of the slot;

[0015] The light-diffusing plate forms a slot corresponding to the card block.

[0016] Optionally, a guide groove is formed on the inner wall of the slot to guide the block closer to / away from the slot;

[0017] The card block is equipped with an elastic element that connects to the slide groove;

[0018] The elastic element always applies a pulling force to the block, causing it to move away from the block.

[0019] Optionally, the card slot forms a first inclined surface along the first direction;

[0020] The card block has a second inclined plane corresponding to the first inclined plane.

[0021] Optionally, a permanent magnet may be installed on the card block;

[0022] An electromagnet is installed inside the chute.

[0023] Optionally, a central processing unit and a power supply for the electromagnet are also provided inside the casing;

[0024] The electromagnet is electrically connected to the central processing unit to control its opening and closing.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The light-diffusing plate can be fixed by the setting of the card blocks and card slots;

[0027] 2. The movement of the card block can be controlled by the setting of permanent magnets and electromagnets, which facilitates the assembly and disassembly of the light-diffusing plate;

[0028] 3. Because the light-diffusing plate is easy to disassemble, the lens mount can be easily installed and removed. Attached Figure Description

[0039] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] This application discloses a filter switching lens mount.

[0041] A filter switching lens mount is disposed within a skin detector; it includes: a skin detector body 100, a lens 1, a support 2, a light-diffusing plate 3, and a filter 4; specifically, the skin detector body 100 includes a shell 102 made of PV material and a mounting groove 5 defined by the shell 102 for mounting the lens 1 mount; specifically, the skin detector body 100 has a scanning unit 6 for scanning human skin; the scanning unit 6 corresponds to the mounting groove 5; wherein, the bottom portion of the mounting groove 5 protrudes to form the support 2, and the shell 102 of the support 2 is integrally formed; two lenses 1 are disposed at intervals on the support 2; the two lenses 1 are a hyperspectral lens 81 and an RGB lens 91.

[0042] Specifically, the outer wall of the main body forms at least one slot 10 that leads into the mounting groove 5. A light-diffusing plate 3, a PCBA board 11, a light-blocking cotton 12, a light filter 4, and a lens 1 are sequentially arranged in the mounting groove 5 along the first direction L to form a lens mount 101. The PCBA board 11 has 400-960 nanometer light. The filter 4 is used to filter light in the horizontal direction to prevent high reflection.

[0043] Specifically, the light-diffusing plate 3 is disposed at the slot 10 and the surface of the light-diffusing plate 3 is flush with the surface of the outer shell 102 on the same horizontal plane; wherein, a locking block 13 is provided on the inner wall of the slot 10, and a locking groove 14 corresponding to the locking block 13 is formed on the side of the light-diffusing plate 3; when the locking block 13 is inserted into the locking groove 14, the light-diffusing plate 3 is limited in the first direction L, thereby limiting the PCBA board 11, the light-blocking cotton 12, the filter 4 and the lens 1.

[0044] More specifically, the inner wall of the slot 10 forms a guide groove 15 for the guide block 13 to approach / move away from the slot 14. An elastic element 16 is provided on the block 13 and connected to the groove 15. The elastic element 16 is a spring, with its two ends fixing the block 13 and the inner wall of the groove 15 respectively, and always providing a pulling force to the block 13 away from the block 13. In the initial state, the end portion of the block 13 near the slot 10 protrudes into the interior of the mounting groove 5. The portion of the block 13 protruding from the inner wall of the mounting groove 5 is defined as the protrusion. A chamfer 18 is formed on the side of the light-diffusing plate 3 near the lens 1, corresponding to the protrusion. During installation, the chamfer 18 abuts against the protrusion, forcing the block 13 to move away from the light-diffusing plate 3. When the block 13 corresponds to the slot 14, the block 13 is embedded in the slot 14 so that the light-diffusing plate 3 is limited in the first direction L.

[0045] More specifically, the slot 14 forms a first inclined surface 19 in the first direction L, and the card block 13 has a second inclined surface 20 corresponding to the first inclined surface 19. A permanent magnet 21 is provided on the card block 13, and an electromagnet 22 corresponding to the permanent magnet 21 is provided in the slide groove 15. The electromagnet 22 is electrically connected to the central processing unit and can control the energization / de-energization of the electromagnet 22. With this configuration, when the electromagnet 22 is energized, it generates a magnetic field that repels the permanent magnet, thus driving the card block 13 to move closer to the light-diffusing plate 3. Under the contact of the first inclined surface 19 and the second inclined surface 20, the light-diffusing plate 3 can move further along the first direction L, thus allowing fine adjustment of the moving distance of the light-diffusing plate 3 in the first direction L. When the energizing current of the electromagnet 22 is changed, a magnetic field that attracts the permanent magnet is generated, causing the card block 13 to disengage from the slot 14, thereby enabling the removal of the light-diffusing plate 3. It can be understood that the ease of removal of the light-diffusing plate 3 also facilitates the replacement of the filter 4.

[0046] In the above scheme, the central processing unit is located inside the casing 102; the power supply 24 is a battery, which is directly connected to the electromagnet 22; it can directly supply power under the control of the central processing unit.

[0047] In the above scheme, the central processing unit is located inside the casing 102; the power source is a battery, which is directly connected to the electromagnet; and it can directly supply power under the control of the central processing unit.
