Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-4 The illustrated device for detecting heavy metals in cosmetics includes a heavy metal detection device 1 and a fixed plate 2. A recess 3 is provided at the center of the heavy metal detection device 1, and an electric sliding module 4 is installed within the recess 3. The fixed plate 2 is installed at the detection port of the heavy metal detection device 1. A rotating mechanism 5 is provided on the top of the fixed plate 2, and a mounting plate 6 is fixedly connected to the top of the rotating mechanism 5. Multiple limiting mechanisms 7 are evenly spaced on the surface of the mounting plate 6, and sample tubes 8 for storing cosmetic samples are engaged inside the limiting mechanisms 7. The heavy metal detection device 1 is a precision instrument, such as an atomic absorption spectrometer, used to determine the content of metal elements in a sample, and is capable of detecting heavy metals in cosmetics. The atomic absorption spectrometer (AAS) consists of a light source, an atomizer, a monochromator, a detector, and a data processor. AAS is a mature, existing technology product. The AAS uses an electric sliding module 4 to adjust the position of the detector. A rotating mechanism 5 automatically adjusts the position of the sample tube 8 placed on the mounting plate 6, positioning it at the detector's detection port. This replaces manual adjustment of the sample tube 8. Furthermore, a limiting mechanism 7 is added to the sample tube 8 to ensure its stability, preventing spillage and leakage of the cosmetic sample inside, thus improving the detection efficiency of the cosmetic heavy metal detection device.

[0024] The mounting plate 6 includes a base plate 61, which is fixed to the top of the rotating mechanism 5. The surface of the base plate 61 has an inner ring 62 and an outer ring 63 arranged from the inside out. A limiting mechanism 7 is installed on the inner ring 62 and the outer ring 63. A positioning plate 64 is installed on the top of the inner ring 62 and the outer ring 63. A positioning groove 65 is formed on the surface of the positioning plate 64 at a position corresponding to the limiting mechanism 7. A limiting sleeve 9 is engaged within the positioning groove 65. The upper end of the sample tube 8 is engaged within the inner cavity of the limiting sleeve 9. The base plate 61 rotates... The moving mechanism 5 drives the rotation, and the inner ring 62 and outer ring 63 are used to fix the limiting mechanism 7. The positioning plate 64 cooperates with the limiting sleeve 9 through the positioning groove 65 to fix the upper end of the sample tube 8. The positioning groove 65 and the limiting sleeve 9 ensure that the sample tube 8 is vertically aligned with the detection port to avoid detection deviation. At the same time, the inner diameter of the limiting sleeve 9 can be selected according to the thickness of the sample tube 8 to limit it. In addition, the limiting sleeve 9 and the positioning groove 65 are detachable, so as to facilitate the replacement and cleaning of the limiting sleeve 9.

[0025] The limiting mechanism 7 includes a sliding sleeve 71, which is respectively embedded in the inner ring 62 and the outer ring 63. A limiting rod 72 is slidably connected to the inner cavity of the sliding sleeve 71. A clamping block 73 is fixedly connected to one end of the limiting rod 72, and a limiting block 74 is fixedly connected to the other end of the limiting rod 72. A spring 75 is sleeved on the surface of the limiting rod 72 near the clamping block 73. The spring 75 pushes the limiting rod 72 to move inward, so that the clamping block 73 clamps the sample tube 8. The adaptive clamping force provided by the spring 75 can clamp sample tubes 8 of different diameters. The limiting block 74 prevents the limiting rod 72 from falling out of the sliding sleeve 71, thus enhancing reliability.

[0026] The rotating mechanism 5 includes a stepper motor 51, which is mounted on the heavy metal detection equipment 1 and located on one side of the fixed plate 2. The output shaft of the stepper motor 51 is fixedly connected to a pinion 52, and a large gear 53 meshes with the surface of the pinion 52. A rotating shaft 54 ​​is fixedly connected to the center of the large gear 53. The bottom of the rotating shaft 54 ​​is rotatably connected to the surface of the fixed plate 2 through a bearing. The upper end of the rotating shaft 54 ​​is fixed at the center of the lower surface of the mounting plate 6. The stepper motor 51 drives the pinion 52, which drives the large gear 53 to rotate. Power is transmitted to the mounting plate 6 through the rotating shaft 54. Subsequently, the mounting plate 6 can automatically adjust the position of the sample tube 8, thereby replacing the manual adjustment of the position of the sample tube 8.

[0027] The outer perimeter of the fixed disk 2 is provided with scale lines 55. The outer side of the bottom of the large gear 53 is fixedly connected with an indicator block 56 that works with the scale lines 55. The indicator block 56 rotates with the large gear 53 and points to the scale lines 55 of the fixed disk 2 to show the rotation angle. This allows the operator to visually confirm the position of the sample tube 8, which is convenient for recording and re-inspection.

[0028] The heavy metal detection device 1 has a placement plate 10 on its outer side. At both ends of the placement plate 10 are placement trays 11 for storing sample tubes 8. The placement trays 11 are used to store sample tubes 8 that are to be tested or have already been tested. They can be separated from the detection area to avoid sample confusion and improve the standardization of laboratory operations.

[0029] In practical use, when testing heavy metals in cosmetics, first set up the heavy metal testing equipment 1, put the cosmetic sample to be tested into the sample tube 8, fix it with the limiting mechanism 7 on the mounting plate 6, and then place the sample tube 8 between the clamping blocks 73 of the limiting mechanism 7. The spring 75 will push the limiting rod 72 to make the clamping blocks 73 clamp the sample tube 8. At the same time, the upper end is further fixed by the limiting sleeve 9 on the positioning plate 64 to ensure that the sample tube 8 is vertical and stable.

[0030] Next, the fixed plate 2 is installed at the detection port of the heavy metal detection equipment 1. The position of the sample tube 8 is adjusted by the rotating mechanism 5. The stepper motor 51 is turned on, which drives the small gear 52 to drive the large gear 53 to rotate. The rotating shaft 54 ​​rotates accordingly, causing the mounting plate 6 to move the sample tube 8. The indicator block 56 at the bottom of the large gear 53 points to the scale line 55 of the fixed plate 2, which makes it easy for the operator to determine the position of the sample tube 8. After the sample tube 8 is adjusted to the detection port, the electric sliding module 4 is started to adjust the detector position of the heavy metal detection equipment 1, and the heavy metal detection of the cosmetic sample in the sample tube 8 begins.

[0031] After the test is completed, the sample tube 8 is placed on the placement trays 11 at both ends of the placement plate 10 to separate the sample to be tested and the sample already tested. Therefore, the heavy metal detection device for cosmetics can effectively replace manual operation by automatically adjusting and fixing the sample, reducing the risk of sample confusion and improving the efficiency and accuracy of heavy metal detection in cosmetics.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
