Description

Technical Field

[0001] The utility model relates to the technical field of yellowing degree comparators, in particular to a skin color yellowing degree comparator. Background Art

[0002] A skin color yellowing degree comparator is a tool for detecting and comparing the yellow tone of the skin. It can help users understand their skin color conditions and carry out corresponding care and adjustment. This device usually analyzes and evaluates the degree of yellow tone of the skin through optical technology.

[0003] The skin color yellowing degree comparator needs to be calibrated (or called calibrated table) to ensure the accuracy and consistency of the test results. Calibration is a process of comparing the readings of the device with known standards or reference values. This usually involves using the standards or reference films provided by the device manufacturer. And the skin color yellowing degree comparator will set multiple calibration standards so that users can more accurately evaluate and manage their skin conditions. When calibrating, it is necessary to select a suitable calibration film from numerous calibration films and place the calibration film under the test probe. However, a large number of calibration films are not easy to collect and store and are prone to loss. Moreover, when the calibration film is taken out of the storage box, the calibration film is easily contaminated, resulting in color difference and thus unable to be used as a reference. Summary of the Utility Model

[0004] The purpose of the utility model is to address the problem that the calibration film is easily contaminated and causes color difference as mentioned in the background art, and to propose a skin color yellowing degree comparator in which the calibration film does not come into contact with the outside world during calibration.

Detailed implementation manners

[0024] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Embodiment

[0026] As Figure 1-2 shown, a skin yellowing degree comparator proposed by the present utility model includes a tester 1 and a test probe 101 fixedly installed on the tester 1, and further includes a protective shell 2 detachably installed on the tester 1, and the test probe 101 is located inside the protective shell 2. The test probe will perform a scanning test on the test part. When the tester 1 is not in use, the protective shell 2 is sleeved on the tester 1 to protect the test probe 101 through the protective shell 2. A partition 5 is fixedly installed inside the protective shell 2, and a through hole 501 is provided on the partition 5. The through hole 501 is coaxially positioned with the test probe 101.

[0027] As Figure 4-5As shown, the skin color comparator further includes a calibration mechanism, which is installed in the protective shell 2. A plurality of calibration pieces are installed on the calibration mechanism, and the calibration mechanism drives different calibration pieces to move below the test probe 101. The calibration mechanism includes two groups of support seats 3 fixedly installed in the protective shell 2, and winding rods 301 rotatably installed on the same group of support seats 3. An installation belt 302 is wound around the two winding rods 301, and a plurality of calibration pieces are fixedly installed on the installation belt 302. A transmission rod 303 is fixedly installed on the winding rod 301. The transmission rod 303 penetrates through one side of the protective shell 2 and extends to the outside of the protective shell 2. A turning hand 304 is fixedly installed on the transmission rod 303, and a linkage belt 305 is fixedly installed on the two winding rods 301. When performing calibration, by rotating one of the turning hands 304 to drive the transmission rod 303 to rotate, the corresponding winding rod 301 can be rotated. Through the setting of the linkage belt 305, the two winding rods 301 can rotate synchronously, thereby driving the installation belt 302 to move, and further driving the calibration pieces on the installation belt 302 to move, so that different calibration pieces can be moved below the through hole 501, and then the calibration pieces are scanned by the test probe 101 to complete the calibration work. It is convenient to replace the calibration pieces, and there is no need to separately store the calibration pieces, preventing the calibration pieces from being easily lost.

[0028] Among them, two installation boxes 405 are fixedly installed on the protective shell 2, a transparent plate 406 is fixedly installed on the installation box 405, the transmission rod 303 penetrates through the installation box 405, a first gear 4 is fixedly installed on the transmission rod 303, the first gear 4 is located inside the installation box 405, a second gear 401 is rotatably installed inside the installation box 405, the first gear 4 and the second gear 401 are meshed with each other, a pointer 402 is fixedly installed on the second gear 401, an installation block 403 is fixedly installed inside the installation box 405, and a plurality of indicating blocks 404 are fixedly installed on the installation block 403. Different colors are provided on the plurality of indicating blocks 404 and correspond to the plurality of calibration pieces one by one. When rotating the turning hand 304 to drive the transmission rod 303 to rotate, the transmission rod 303 will drive the first gear 4 to rotate. Through meshing transmission, the second gear 401 can be rotated. The rotation of the second gear 401 will drive the pointer 402 to rotate. The rotating pointer 402 will face different indicating blocks 404. By synchronously rotating the pointer 402 with the winding rod 301, the color of the indicating block 404 pointed to by the pointer 402 can be used to judge the color of the calibration piece corresponding to the test probe 101 at this time.

[0029] Further, as Figure 2-3As shown, the skin yellowing degree comparator further includes a plugging mechanism. The plugging mechanism is installed in the protective shell 2 and plugs the through hole 501 when the tester 1 is separated from the protective shell 2. The plugging mechanism includes two plugging blocks 6 slidably installed on the partition plate 5, two connecting rods 601 fixedly installed on the plugging blocks 6, a sliding rod 605 slidably installed on the partition plate 5, a pressing block 603 fixedly installed on the sliding rod 605, and a connecting rod 602 rotatably installed on the connecting rod 601. The other end of the connecting rod 602 is rotatably connected to the pressing block 603. A spring 604 is fixedly installed between the connecting rods 601 on different plugging blocks 6. When the protective shell 2 is combined with the tester 1, the outside of the test probe 101 will contact the pressing block 603 and drive the pressing block 603 to move downward along the axis of the sliding rod 605. The downward moving pressing block 603 will drive the connecting rod 602 to rotate, and the rotating connecting rod 602 will push the two plugging blocks 6 away from each other. The two mutually separated plugging blocks 6 will move away from above the through hole 501. At this time, the test probe 101 can scan the calibration piece through the through hole 501. When the protective shell 2 is separated from the tester, under the action of the spring 604, the two plugging blocks 6 will approach each other, and at this time, the two plugging blocks 6 will plug the through hole 501, thereby preventing foreign impurities from contacting the calibration piece and preventing the calibration piece from being contaminated.

[0030] Wherein, one of the plugging blocks 6 is provided with a convex block, and the other plugging block 6 is provided with a groove corresponding to the convex block. Two groups of sliding grooves are provided on the partition plate 5, and the plugging blocks 6 are slidably connected to the sliding grooves. By combining the convex block and the groove, the tightness between the two plugging blocks 6 can be improved, and the plugging performance can be improved.

[0031] Working principle: When the protective shell 2 is combined with the tester 1, the outer side of the test probe 101 will contact the pressing block 603 and drive the pressing block 603 to move downward along the axial direction of the sliding rod 605. The downward-moving pressing block 603 will drive the connecting rod 602 to rotate. The rotating connecting rod 602 will push the two plugging blocks 6 on both sides away from each other. The two plugging blocks 6 moving away from each other will leave the upper part of the through hole 501. By rotating one of the turning hands 304 to drive the transmission rod 303 to rotate, the corresponding winding rod 301 can be rotated to drive the mounting belt 302 to move, and then drive the calibration piece on the mounting belt 302 to move. The color of the calibration piece corresponding to the test probe 101 at this time is judged by observing the color of the indicating block 404 pointed to by the pointer 402. Thus, it is convenient to move different calibration pieces to the lower part of the through hole 501, and then the calibration piece is scanned by the test probe 101 to complete the calibration work. It is convenient to replace the calibration piece without the need for separate storage of the calibration piece, preventing the calibration piece from being easily lost. When the protective shell 2 is separated from the tester, under the action of the spring 604, the two plugging blocks 6 will approach each other. At this time, the two plugging blocks 6 will plug the through hole 501, thereby preventing external impurities from contacting the calibration piece and preventing the calibration piece from being contaminated.
