A water bottle 14 is placed on the top end of the mounting plate 3, and a connecting tube 15 is installed on the top end of the water bottle 14. A protective cover 16 is hinged to the front side of the spectrometer body 1. A limiting plate 24 is slidably connected to the bottom end of the inner side of the spectrometer body 1. A second sliding groove 25 matching the limiting plate 24 is opened on the inner wall of the spectrometer body 1.

An atomic absorption spectrometer for inorganic heavy metal detection is a high-precision, high-sensitivity analytical instrument that can quickly and accurately detect multiple metal elements in a sample. Its basic structure mainly consists of a light source, an atomizer, a spectroscopic system, and a detection system. The light source emits light of a specific wavelength, the atomizer converts the sample into atomic vapor, the spectroscopic system disperses the light radiation into a spectrum of different wavelengths, and finally, the detection system converts the optical signal into an electrical signal and processes the data. Its operating principle is based on the phenomenon of atomic absorption, that is, when light of a specific wavelength passes through atomic vapor, ground-state atoms absorb the light corresponding to their specific energy level transitions, and the amount of absorbed light is proportional to the number of atoms in the atomic vapor. By measuring the amount of light absorbed, the content of elements in the sample can be inferred. Atomic absorption spectrometers are widely used in scientific research and industrial fields and play an important role in the detection of inorganic heavy metals.

[0025] refer to Figure 1 A rectangular opening 17 is provided on the front side of the protective cover 16. The rectangular opening 17 communicates with the inside of the spectrometer body 1.

A handle 19 is fixedly connected to the front side of the protective cover 16. The handle 19 is concave in shape, and the corners of the handle 19 are arc-shaped. Because of the opening of the rectangular opening 17, the user can directly view the inside of the spectrometer body 1 through the transparent glass 18 without opening the protective cover 16, which is conducive to the user's constant observation of the inside of the spectrometer body 1. The installation of the handle 19 also facilitates the user to open or close the protective cover 16 later.

[0026] refer to Figures 1 to 5A locking block 22 is fixedly connected to the bottom end of the protective plate 20.

A first telescopic rod 11 is fixedly connected to one side of the first limiting frame 4, and one side of the first telescopic rod 11 is fixedly connected to the other side of the placement plate 2. The first screw 9... Located on the inner side close to the first telescopic rod 11, in order to improve the stability of the water bottle 14 position, the user can turn the first screw 9, and the first rotating shaft 8 can make the end of the first screw 9 rotate in place, and the second limiting frame 6 will move along the first sliding groove 5. Under the mutual clamping of the first limiting frame 4 and the second limiting frame 6, the position of the water bottle 14 can be effectively limited to prevent the water bottle 14 from being displaced. The first telescopic rod 11 can provide secondary support and limitation on one side of the second limiting frame 6 without hindering the adjustment of the position of the second limiting frame 6, which can effectively improve the stability of the position adjustment of the second limiting frame 6, facilitate the adjustment of the spacing, and also facilitate the user to limit and clamp water bottles 14 of different sizes. It also facilitates the user to disassemble and replace the water bottle 14 later.

[0028] refer to Figure 1 and Figure 2Rubber pads 7 are fixedly connected to one side of the first limiting frame 4 and the other side of the second limiting frame 6. The rubber pads 7 cover one side of the first limiting frame 4 and the other side of the second limiting frame 6. A groove 12 is provided at the top of the mounting plate 3. An anti-slip pad 13 is fixedly connected to the bottom of the inner side of the groove 12. The anti-slip pad 13 covers the inner side of the groove 12. The top of the anti-slip pad 13 is in contact with the bottom of the water bottle 14. Due to the presence of the rubber pad 7, the rubber pad 7 has good elasticity and anti-slip ability. While avoiding collision between the water bottle 14 and the first limiting frame 4, it can also effectively improve the stability of the water bottle 14 position. The installation of the anti-slip pad 13 can increase the friction at the top of the mounting plate 3, thereby making the water bottle 14 position more stable, and further improving the stability of the water bottle 14 position.

[0029] refer to Figure 3 and Figure 4 A second telescopic rod 29 is fixedly connected to the top of the limiting plate 24.

The bottom end of the sleeve rod is fixedly connected to the top of the limiting plate 24. The top end of the movable rod is fixedly connected to the top inner side of the spectrometer body 1. Due to the presence of the second telescopic rod 29, the second telescopic rod 29 can provide secondary support and limitation for the top of the limiting plate 24 without hindering the adjustment of the height of the limiting plate 24, thereby effectively improving the stability of the height adjustment of the limiting plate 24.

[0030] Operating principle and advantages: During use, due to the rectangular opening 17, the user can directly view the inside of the spectrometer body 1 through the transparent glass 18 without opening the protective cover 16, thus facilitating constant observation of the inside of the spectrometer body 1. The installation of the handle 19 also facilitates the user's opening or closing of the protective cover 16. Due to the presence of the locking block 22, the position of the protective plate 20 can be effectively fixed, thus preventing the protective plate 20 from shifting. When it needs to be opened, simply pull the protective plate 20 with the handle 21 to remove the locking block 22. When the spectrometer body 1 is used for a long time... When cleaning the interior is required, first open the protective cover 16 using the hinge principle, then remove the protective plate 20 using the snap-fit ​​principle, and then turn the second screw 28. The second rotating shaft 26 can cause the end of the second screw 28 to rotate in place, and the limiting plate 24 will be pulled accordingly, allowing the limiting plate 24 to slide upward along the second slide groove 25. At the same time, the instruments that need to be cleaned inside the spectrometer body 1 can be pushed to a position that is easier to clean, thereby achieving the purpose of facilitating the cleaning of the interior of the spectrometer body 1. To improve the stability of the water bottle 14, the user can turn the first screw 9. The first rotating shaft 8 can cause the first screw 9 to rotate in place. The end of rod 9 rotates in place, and the second limiting frame 6 moves along the first sliding groove 5. Under the mutual clamping of the first limiting frame 4 and the second limiting frame 6, the position of the water bottle 14 can be effectively limited to prevent displacement. The first telescopic rod 11 can provide secondary support and limitation on one side of the second limiting frame 6 without hindering the adjustment of its position. This effectively improves the stability of the position adjustment of the second limiting frame 6, facilitates the adjustment of the spacing, and allows users to clamp water bottles 14 of different sizes. It also facilitates the user's later disassembly and replacement of the water bottle 14. The presence of 7, with its rubber pad 7 having good elasticity and anti-slip ability, not only prevents the water bottle 14 from colliding with the first limiting frame 4, but also effectively improves the stability of the water bottle 14's position clamping. The installation of its anti-slip pad 13 can increase the friction at the top of the mounting plate 3, thereby making the water bottle 14's position more stable, and further improving the stability of the water bottle 14's position fixing. Due to the presence of the second telescopic rod 29, the second telescopic rod 29 can provide secondary support and limitation for the top of the limiting plate 24 without hindering the adjustment of the height of the limiting plate 24, thereby effectively improving the stability of the height adjustment of the limiting plate 24.
