Abstract
Description
Technical Field
[0001] This utility model relates to the field of gemstone testing technology, specifically a gemstone fading test device. Background Technology
[0002] As high-value natural or synthetic materials, the color stability of gemstones directly determines their collectible value, commercial value, and lifespan. However, during natural storage or use, gemstones are susceptible to environmental factors such as light, temperature, and humidity, resulting in irreversible fading. For example, some gemstones containing coloring elements such as chromium and iron will lighten in color due to changes in the valence state of ions in the crystal lattice when exposed to strong ultraviolet light for a long time. High temperatures may accelerate the decomposition of pigments inside the gemstone, while high humidity may cause surface oxidation or chemical corrosion, further exacerbating fading.
[0003] Existing gemstone fading experimental setups have significant limitations in light source design: most setups are equipped with only a single type of light source. To compare the effects of different light sources, such as ultraviolet light and white light, on gemstone samples, researchers often need to prepare multiple experimental setups corresponding to different light sources. This approach not only significantly increases experimental costs but also compromises the accuracy of comparative experimental data due to subtle differences in environmental parameters between different setups. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a gemstone fading test device, which allows for quick replacement of light sources by disassembling and assembling components, and can complete comparative experiments with different light sources without the need for multiple devices, thereby reducing costs, avoiding mechanical error interference, and ensuring data reliability.

The disassembly assembly includes: an opening, a threaded rod, and a nut.
[0006] Optionally, the top of the disassembly plate and the cover plate are provided with four openings, the openings are provided with threaded rods, and the outside of the threaded rods are threaded with nuts. Positioning blocks are installed on both sides of the bottom of the cover plate, and the top of the experimental platform is provided with multiple positioning grooves that fit with the positioning blocks. The disassembly assembly consisting of the openings, threaded rods and nuts is used for disassembling and assembling the ultraviolet lamp.
[0007] Optionally, each of the four experimental tanks is equipped with a placement plate, and a handle is installed on the top of the placement plate. Electric heating plates are installed on both sides of the inner wall of each of the four experimental tanks. A liquid storage tank is opened inside the experimental platform. A liquid inlet pipe is installed on one side of the outer end of the liquid storage tank. A plug is threadedly connected to the inlet of the liquid inlet pipe. Multiple vent holes are opened between the four experimental tanks and the liquid storage tank. Solenoid valves are installed inside the multiple vent holes. Air outlet holes are opened on the top of the four disassembly plates and the four cover plates. An atomizer is installed on one side of the inner wall of the liquid storage tank. A partition is installed inside each of the four experimental tanks. Rotating plates are rotatably connected to both sides of the outer end of the experimental platform via hinges. The liquid inlet pipe is used to add liquid into the liquid storage tank.
[0008] The beneficial effects of this utility model are: The advantage of this invention is that the ultraviolet lamp and the white LED lamp can be quickly replaced by disassembling and assembling the components. The comparison experiment of different light sources can be completed without purchasing multiple additional devices. This design not only greatly reduces the experimental cost, but also avoids the interference of mechanical errors between multiple devices on parameters such as light intensity and angle, ensuring the consistency and reliability of the comparison data.

Detailed Implementation
[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0016] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0017] like Figures 1-5 As shown, a gemstone fading test apparatus includes: a test platform 1, with four test slots 101 on the top of the test platform 1, each of the four test slots 101 having a cover plate 102 on the top, and four disassembly plates 103 installed at the bottom of the cover plate 102. Multiple ultraviolet lamps 104 are installed at the bottom of the disassembly plates 103, and a disassembly assembly is provided between the ultraviolet lamps 104 and the disassembly plates 103 for disassembling and assembling the ultraviolet lamps 104. The disassembly assembly includes: an opening 2, a threaded rod 201, and a nut 202.
[0018] The experimental platform 1 has a control panel installed on one side of its outer end. The control panel controls the start and stop of the electric heating plate 402, solenoid valve 601, atomizer 603, ultraviolet lamp 104, and white LED lamp, respectively, so as to realize the unified or independent control of multiple sets of experimental conditions, greatly improve the operating efficiency, and ensure the accuracy and consistency of experimental parameter settings. The control panel, electric heating plate 402, solenoid valve 601, atomizer 603, ultraviolet lamp 104, and white LED lamp are all powered by external power sources. The control panel, electric heating plate 402, solenoid valve 601, atomizer 603, ultraviolet lamp 104, and white LED lamp are all existing structures, and this application has not improved these structures. Therefore, this application does not describe the detailed usage methods of these structures.
[0019] The disassembly plate 103 and the cover plate 102 each have four openings 2 at the top. A threaded rod 201 is installed inside the opening 2, and a nut 202 is threaded to the outside of the threaded rod 201. By inserting the threaded rod 201 into the opening 2 and tightening the nut 202, the disassembly plate 103 and the ultraviolet lamp 104 can be securely connected to the cover plate 102. Loosening the nut 202 and pulling out the threaded rod 201 can quickly separate the components, making it easy to replace different light sources and meet the experimental requirements for adjusting the type of light.
[0020] The cover plate 102 has positioning blocks 3 installed on both sides of its bottom. The top of the experimental platform 1 has multiple positioning grooves 301 that fit with the positioning blocks 3. The positioning blocks 3 fit with the positioning grooves 301. Their function is to accurately position the relative position of the cover plate 102 and the experimental platform 101, so as to ensure that the cover plate 102 can be stably covered on the top of the experimental platform 101 and avoid external light from penetrating due to the offset of the cover, which would interfere with the stability of the light variable in the experiment.
[0021] Each of the four experimental tanks 101 is equipped with a placement plate 4, and a handle 401 is installed on the top of the placement plate 4. Electric heating plates 402 are installed on both sides of the inner wall of the four experimental tanks 101. The handle 401 on the top of the placement plate 4 makes it easy for the experimenter to quickly pick up and put down the placement plate 4 and the gemstone sample on it, improving the ease of operation. The electric heating plate 402 can change the temperature inside the experimental tank 101 by adjusting the power, so as to meet the needs of gemstone fading experiments under different temperature conditions and provide a controllable temperature environment for exploring the influence of temperature factors on gemstone fading.
[0022] The experimental platform 1 has a liquid storage tank 5 inside, and an inlet pipe 501 is installed on one side of the outer end of the liquid storage tank 5. A plug is threadedly connected to the inlet of the inlet pipe 501. The liquid storage tank 5 inside the experimental platform 1 is used to store the liquid required for the experiment, providing a material basis for adjusting the humidity or chemical environment in the experimental tank 101. The inlet pipe 501 on one side of the outer end of the liquid storage tank 5 facilitates the injection of liquid into the liquid storage tank 5. The plug threadedly connected to the inlet of the inlet pipe 501 can seal the pipe opening after the liquid is injected, preventing the liquid in the liquid storage tank 5 from evaporating or external impurities from entering, ensuring the purity of the stored liquid and the stability of the experimental environment.
[0023] Multiple vent holes 6 are provided between the four experimental tanks 101 and the storage tank 5. Each vent hole 6 is equipped with a solenoid valve 601. Vent holes 602 are provided on the tops of the four disassembly plates 103 and the four cover plates 102. An atomizer 603 is installed on one side of the inner wall of the storage tank 5. The multiple vent holes 6 between the four experimental tanks 101 and the storage tank 5 serve as channels for humid air from the storage tank 5 to enter the experimental tanks 101, providing a path for adjusting the humidity or chemical environment within the experimental tanks 101. The solenoid valves 601 inside the vent holes 6... Valve 601 can independently control the opening and closing of each vent 6, realizing precise regulation of the environment inside different experimental tanks 101, and meeting the differentiated needs of multiple sets of comparative experiments. The vents 602 on the top of the four disassembly plates 103 and the four cover plates 102 are used to discharge excess gas in the experimental tank 101. The atomizer 603 on one side of the inner wall of the liquid storage tank 5 can convert the liquid in the liquid storage tank 5 into humid air, providing an air source for changing the humidity in the experimental tank 101. Together with the vent 6 and the solenoid valve 601, they form a complete humidity regulation system.
[0024] Each of the four experimental tanks 101 is equipped with a partition 7. The two outer sides of the experimental platform 1 are connected to a rotating plate 701 via hinges. The partition 7 is made of high-temperature resistant glass. The partition 7 installed inside the four experimental tanks 101 is made of high-temperature resistant glass. Due to its transparency, it is easy for the experimenters to clearly see the state of the gemstone samples in the tank. The rotating plate 701 connected to the two outer sides of the experimental platform 1 via hinges can be opened for convenient observation from the outside when the experimenters need to view the gemstone samples. When closed, it can reduce external interference, thus balancing the convenience of observation with the stability of the experimental environment.
[0025] Working principle: When using this device, before the experiment, place the gemstone sample on the placement plate 4 inside the experimental tank 101, and then cover the top of the experimental tank 101 with the positioning block 3 and the positioning groove 301 to isolate external light interference and avoid the influence of ambient light on the stability of the illumination variable during the experiment. If it is necessary to change the illumination type, first loosen the nut 202 at the connection between the disassembly plate 103 and the ultraviolet lamp 104, pull out the threaded rod 201, and remove the disassembly plate 103 and the ultraviolet lamp 104; then place the disassembly plate 103 with the white LED light at the bottom of the cover plate 102, pass one end of the threaded rod 201 through the opening 2, and tighten the nut 202 on the outside of the threaded rod 201 to complete the fixation.
[0026] During the experiment, the number of white LED lights and ultraviolet lamps 104 installed at the bottom of the four cover plates 102 can be selected according to needs. The gemstone samples are then placed on top of the placement plates 4 within the experimental tank 101. After the specified irradiation time is reached, the color change of the gemstones is observed with the naked eye. Simultaneously, photographs are taken under the same lighting and background conditions, and these photographs are continuously taken at a fixed cycle over 30 days to record the color change process. By summarizing the ΔE values of each gemstone over 30 days and plotting color difference curves for different time periods, the degree of fading can be quantitatively analyzed, forming complete experimental data.
[0027] In terms of environmental variable control, the electric heating plate 402 on the inner wall of the experimental tank 101 can adjust the temperature inside the tank; the water in the storage tank 5 is heated by the atomizer 603 to generate humid air, which enters the experimental tank 101 through the vent 6 to change the humidity, and excess moisture is discharged through the vent 602. With the help of the solenoid valve 601, the opening and closing of each vent 6 can be controlled separately. Therefore, the four experimental tanks 101 can be independently set with different conditions such as light, temperature, and humidity to realize multiple sets of comparative experiments and accurately explore the effects of different environmental factors on gemstone fading.
