Description

Technical Field

[0001] This utility model relates to the field of photometer technology, and more specifically, to a spectrophotometer with a desiccant that is easy to replace. Background Technology

[0002] A spectrophotometer is an analytical instrument based on the principle of light absorption. Its core components include a light source, monochromator, sample cell, and detector. It achieves quantitative analysis by measuring the degree to which a substance absorbs light of a specific wavelength. Its theoretical basis is Beer-Lambert's Law, which states that absorbance is directly proportional to sample concentration and optical path length. Spectrophotometers can be categorized by measurement range, including ultraviolet-visible, infrared, and fluorescence types. They are widely used in chemistry, biology, and medicine, and are key tools for scientific research and quality control. The working principle of a spectrophotometer is based on the interaction between light and matter: the light source emits composite light, which is decomposed into monochromatic light of specific wavelengths by the monochromator. This monochromatic light is absorbed by the analyte in the sample cell, and the remaining light reaches the detector and is converted into an electrical signal. According to Beer-Lambert's Law, absorbance is linearly related to the substance concentration. By measuring the absorbance and comparing it with a standard curve, the sample concentration can be calculated. The entire process achieves quantitative analysis of substances through the conversion of light signals to electrical signals. Since the method of replacing the desiccant directly affects the efficiency of the replacement operation, rapid replacement is necessary.

[0003] In related technologies, during the use of a spectrophotometer, the cover at the top of the desiccant container is typically connected and opened using multiple bolts, allowing the desiccant inside to be removed and replaced.

[0004] However, in the current use of spectrophotometers, the multiple bolts connecting the opening and closing mechanism require users to rotate and align the desiccant cover, and then repeatedly rotate multiple bolts to connect it. This makes the desiccant replacement operation inconvenient and affects the convenience and efficiency of the desiccant replacement operation. Utility Model Content

[0030] Reference Figures 1-4 This utility model provides a technical solution: a spectrophotometer that facilitates desiccant replacement, including a spectrophotometer 1 and a desiccant replacement mechanism. A button 2 is installed on the right side of the bottom front of the spectrophotometer 1, and a sample cover 3 is installed on the front top of the spectrophotometer 1. This can form a space for desiccant replacement and a medium for quick opening and closing, so that users can quickly replace the desiccant and avoid the need to repeatedly turn the bolt and align it when replacing the desiccant. Therefore, it improves the convenience and efficiency of desiccant replacement.

[0031] Reference Figures 1-4 In a preferred embodiment, the desiccant replacement mechanism includes a replacement slot 4 located at the rear of the top of the spectrophotometer 1. A replacement cover 5 is movably connected inside the replacement slot 4. A receiving slot 6 is located at the bottom of the inner wall of the replacement slot 4, and a receiving cylinder 7 is movably connected inside the receiving slot 6. A replacement closing mechanism is movably connected to the top of the receiving cylinder 7. By pushing the replacement cover 5 backward, the replacement slot 4 is moved out, opening the receiving slot 6. Then, the receiving cylinder 7 is removed, and the old desiccant inside the receiving cylinder 7 is poured out, allowing new desiccant to be placed and filled into the receiving cylinder 7. The desiccant replacement and closing mechanism includes a closing cover 8, a closing groove 9, and a closing block 10. The closing cover 8 is movably connected to the top inside the container 7. The closing groove 9 is opened on the outside of the closing cover 8. The closing block 10 is movably connected to both sides inside the closing groove 9. The outside of the closing block 10 is fixedly connected to the inner wall of the container 7, which can close the top of the container 7, so that the user can close the desiccant inside the container 7 stably and avoid the container 7 being difficult to close during use, thus improving the convenience of closing the container 7.

[0032] Reference Figures 2-3 In a preferred embodiment, by providing offset openings 11 on both sides of the bottom of the closing cover 8, with the top of the offset openings 11 connected to the bottom of the closing groove 9, space can be provided for the closing block 10 to enter and exit the closing groove 9, avoiding the situation where the closing block 10 is difficult to enter and exit the closing groove 9 during use, thus improving the smoothness of operation of the closing block 10. On the outer side of the inner wall of the receiving cylinder 7, openings 12 are provided, located at the bottom of the closing cover 8, providing space for the receiving cylinder 7 to open and exit air, avoiding the situation where the air circulation space of the receiving cylinder 7 is insufficient during use, thus improving the air circulation effect of the receiving cylinder 7.

[0033] Reference Figures 2-4In a preferred embodiment, a connecting groove 13 is provided on the front side of the inner wall of the replacement groove 4, and a connecting strip 14 located inside the connecting groove 13 is fixedly connected to the front side of the replacement cover 5, which can connect the replacement cover 5 and the replacement groove 4, thus improving the connection effect between the replacement cover 5 and the replacement groove 4. A magnetic strip 15 is embedded and connected to the front side of the inner wall of the connecting groove 13, and a magnetic strip 16 that is magnetically connected to the magnetic strip 15 is embedded and connected to the front side of the connecting strip 14. The magnetic positioning between the replacement cover 5 and the replacement groove 4 can be performed through the connecting strip 14, thus improving the connection stability of the replacement cover 5.

[0034] Reference Figures 2-4 In a preferred embodiment, a movable groove 17 is provided at the bottom of the replacement cover 5, and a movable strip 18 is movably connected inside the movable groove 17. The bottom of the movable strip 18 is fixedly connected to the top of the closing cover 8, which provides the user with an operating medium for rotating the closing cover 8, thus improving the ease of operation of closing the cover 8. A force-applying strip 19 is movably connected to the top of the replacement groove 4, and the bottom of the force-applying strip 19 is fixedly connected to the top of the replacement cover 5, which provides the user with a force-applying medium for sliding the replacement cover 5, thus improving the ease of force application for the replacement cover 5.

[0035] Specifically, the working process or principle of this spectrophotometer with easy desiccant replacement is as follows: When the desiccant needs to be replaced, the force bar 19 applies a rearward pushing force to the replacement cover 5, moving it out of the replacement slot 4, thus opening the receiving slot 6. During this process, the connecting bar 14 moves rearward along with the replacement cover 5 out of the connecting slot 13. At this time, the magnetic strip 16 moves with the connecting bar 14 and separates from the magnetic suction bar 15, preparing for subsequent magnetic positioning of the replacement cover 5 and the replacement slot 4 via the connecting bar 14. Simultaneously, the movable bar 18 moves out of the replacement cover 5 through the movable slot 17, allowing the user to subsequently rotate the closing cover 8 via the movable bar 18 to move the replacement cover 5 out of the replacement slot 4. Holding the movable bar 18, the closing cover 8 is moved. Through the closing block 10 and the closing groove 9, the receiving cylinder 7 is removed from the receiving groove 6. Then, the movable bar 18, in conjunction with the closing cover 8, drives the misalignment port 11 to rotate. Since the movable bar 18 is parallel to the misalignment port 11, the user can clearly see the position of the misalignment port 11 through the movable bar 18. When the directions on both sides of the movable bar 18 are aligned with the closing block 10, it means that the misalignment port 11 is aligned with the closing block 10. Then, holding the movable bar 18, an upward pulling force is applied to the closing cover 8 to remove the closing cover 8 and open the receiving cylinder 7. Then, holding the receiving cylinder 7, the old desiccant inside is poured out, and the new desiccant from the outside is placed inside the receiving cylinder 7 to fill it. This completes the desiccant replacement operation.

[0036] It should be noted that the spectrophotometer 1, button 2 and sample cover 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
