[0002] Sealed water sample preservation bottles are containers specifically designed for collecting, preserving, and transporting water samples (such as river water, lake water, seawater, drinking water, etc.) to ensure that the water samples are not contaminated by external factors and remain in their original state from collection to analysis.

[0003] The sealed water sample preservation bottle features a special sealing design between the cap and the bottle opening, such as rubber gaskets and screw fasteners, to ensure that the water sample will not leak and to prevent outside air and impurities from entering the bottle.

[0004] Existing sealed water sample preservation bottles are used by opening the cap and inserting the water sample into the bottle through the opening on the bottle body for preservation. However, impurities such as suspended solids and particulate matter in the water sample cannot be effectively removed during collection and preservation. If these impurities are directly put into the bottle without treatment, it will affect the accuracy of subsequent water quality analysis results and reduce the practicality of the preservation bottle.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a sealed water sample preservation bottle, including a bottle body 1 and a bottle cap 3;

[0030] A filter device is installed on bottle 1;

[0031] The filtration device includes a mounting frame 11 and a filter plate 13. The lower outer wall of the mounting frame 11 is slidably connected to the inside of the upper opening of the bottle body 1. Four protective shells 4 are fixedly connected to the upper outer wall of the bottle body 1, and each of the four protective shells 4 has a pull rod 2 slidably connected to its outer wall. Four first limiting block grooves 7 are opened on the upper inner wall of the bottle body 1, and each of the four first limiting block grooves 7 has a limiting block 6 slidably connected inside. The inside of each of the four protective shells 4 communicates with the inside of the corresponding first limiting block groove 7. The lower outer wall of the mounting frame 11 has four second... The four limiting blocks 6, one end of which is close to the second limiting block groove 9, slides into the interior of the bottle body 1 and contacts the inner wall of the corresponding second limiting block groove 9. The four pull rods 2, one end of which is close to the limiting block 6, slides into the interior of the first limiting block groove 7 and is fixedly connected to one end of the corresponding limiting block 6. The filter plate 13 is installed inside the mounting frame 11. The outer wall of each of the four pull rods 2 is fitted with a return spring 5. The two ends of the four return springs 5 ​​are fixedly connected to one end of the corresponding limiting block 6 and the inner wall of the protective shell 4, respectively.

[0032] Among them, a sealing ring 12 is installed on the lower outer side of the mounting frame 11. The outer wall of the sealing ring 12 contacts the upper inner wall of the bottle body 1. The upper inner wall of the mounting frame 11 is provided with an internal thread 10. The lower outer wall of the bottle cap 3 is provided with an external thread 8. The bottle cap 3 and the mounting frame 11 are engaged by the external thread 8 and the mounting frame 11 by the internal thread 10 on the upper inner wall.

[0033] Furthermore, when using this device, when a water sample is placed inside the bottle body 1, the water sample is processed by the filter plate 13 installed inside the mounting frame 11 before entering the bottle body 1 for preservation. This effectively improves the quality of water sample preservation and the accuracy of water sample testing. Then, the bottle cap 3 is installed on the mounting frame 11 by the external thread 8 and the internal thread 10. When it is necessary to remove the filter plate 13, the pull rod 2 is pulled to move in the opposite direction, which causes the limiting block 6 to move in the opposite direction and at the same time causes the return spring 5 to retract. Then, the limiting block 6 moves in the opposite direction so that its other end outer wall is disengaged from the inside of the second limiting block groove 9. Then, the mounting frame 11 is pulled upward to remove the mounting frame 11 and the filter plate 13 from the bottle body 1.

[0034] When a water sample is introduced into the bottle 1 through the filtration device, the water sample is processed by the filter plate 13 installed inside the mounting frame 11 before entering the bottle 1 for preservation. This effectively improves the quality of water sample preservation and the accuracy of water sample testing, thereby effectively improving the practicality and effectiveness of the bottle 1, while preventing impurities in the water sample from entering the bottle 1.

[0035] Structural Description: Bottle 1: The main body is a cylindrical or conical container with an external thread 8 at the top opening and a closed structure at the bottom. The interior is used to store filtered water samples. It is fixed by screwing the external thread 8 into the internal thread 10 of the mounting frame 11 to form a sealed cavity.

[0036] Mounting and fixing frame 11: Annular frame structure, with an internal thread 10 on the inner side of the top, an open design at the bottom, and a filter plate 13 embedded inside. The side walls are symmetrically provided with limiting blocks 6 and second limiting block grooves 9. The top is screwed into the external thread 8 of the bottle body 1 through the internal thread 10, and the bottom is locked into the second limiting block groove 9 of the bottle body 1 through the limiting block 6.

[0037] Filter plate 13: Made of multi-layer filter screen or activated carbon material, it is fixed inside the mounting frame 11, covering the water inlet channel. It is embedded in the mounting frame 11 through a ring to intercept impurities and microorganisms during water sample pretreatment, thereby improving the water sample preservation quality and detection accuracy.

[0038] Bottle cap 3: Independent sealing cap with internal thread 10 and anti-slip texture designed on the outside. It can be screwed into the external thread 8 of the mounting frame 11 through the internal thread 10 to seal the bottle mouth.

[0039] External thread 8 and internal thread 10: External thread 8 is a standard thread located on the top outer wall of the bottle body 1, and internal thread 10 is a standard thread located on the top inner side of the mounting frame 11 and inside the bottle cap 3. The three-level connection of the bottle body 1, the mounting frame 11, and the bottle cap 3 is achieved by screwing them together. The standardized threads ensure quick installation and stable sealing, and are pressure resistant and leak-proof.

[0040] Pull rod 2: The operating rod is symmetrically set on the outer wall of the bottle body 1 and is linked with the limit block 6. The internal return spring 5 is integrated. When the pull rod 2 is pulled, the limit block 6 moves laterally and disengages from the second limit block groove 9. The installation and fixing frame 11 can be unlocked by one hand, which simplifies the disassembly process and improves efficiency.

[0041] Limiting block 6: A symmetrically arranged protruding structure on the side wall of the mounting frame 11, which can slide laterally and is locked into the second limiting block groove 9 of the bottle body 1 by the elastic force of the return spring 5, forming a mechanical lock, enhancing the stability of the mounting frame 11 and preventing it from loosening and falling off during use.

[0042] Return spring 5: A helical spring fitted inside the pull rod 2, providing elastic return force, and automatically returning to its original position after being compressed and contracted.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
