[0004] However, in actual use, the above-mentioned device is connected together by multiple devices and placed on a desktop for analysis. Therefore, in actual use, there is a problem of being too complicated and inconvenient, which is not conducive to the rapid preparation and sampling analysis of lithium hexafluorophosphate.

[0008] The interior of the tube body is slidably connected to a drawer, which is used to draw the solution dissolved in lithium hexafluorophosphate from the liquid extraction cap into the interior of the tube body, and a notch is provided on the rod portion of the drawer;

[0009] A detachable electronic detector and a storage barrel are installed on the top of the tube, the electronic detector is used to detect the solubility of lithium hexafluorophosphate in the solution, and the storage barrel is used to store the lithium hexafluorophosphate crystals obtained after preparation;

[0010] The detection end of the electronic detector is adapted to the notch, and a discharge component for filtering the residue of the lithium hexafluorophosphate crystal solution is provided at the middle end of the bottom of the tube body.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The lithium hexafluorophosphate preparation sampling and analysis device cleverly integrates the functions of liquid extraction, filtration, dissolution detection, and discharge, significantly improving the convenience and efficiency of operation. This is specifically reflected in the following aspects:

[0021] First, the device features a pull-out design. The reciprocating motion of the pull-out rod allows for easy extraction of the lithium hexafluorophosphate solution and pushes it into the tube. A force-bearing disc at one end of the pull-out rod allows the operator to easily apply tension, while a web at the other end ensures a good seal with the tube interior, preventing solution leakage. Furthermore, a notch allows for easy insertion of an electronic detector into the tube to test the solubility of lithium hexafluorophosphate in the solution.

[0022] Secondly, the device is equipped with a connecting pipe and an injection valve pipe at the top of the tube body, which are used to connect the electronic detector and the storage barrel respectively. The threaded design of the connecting pipe and the electronic detector makes the connection between the two both stable and easy to disassemble and clean. The injection valve pipe is connected to the storage barrel, which facilitates the storage of the prepared lithium hexafluorophosphate crystals for subsequent analysis.

[0023] Furthermore, the discharge assembly at the bottom of the device includes a discharge channel, a locking plate and a filter. The design of the discharge channel allows the solution and residue inside the tube to be discharged smoothly, while the locking plate can close the discharge channel when needed to prevent the solution from leaking. The filter effectively filters out the solid residue in the solution to ensure the purity of the discharged solution.

[0024] Furthermore, the design of the storage barrel takes practicality and safety into full consideration. The locking cap at the barrel mouth effectively prevents external impurities from entering the barrel, ensuring the purity of the lithium hexafluorophosphate crystals. Furthermore, the protective coating on the interior of the barrel resists chemical corrosion, extending the service life of the storage barrel. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] It should be noted that in this application, the electronic detector 4 is a conventional commercially available lithium hexafluorophosphate concentration detection device, such as a portable lithium hexafluorophosphate concentration analyzer, which can detect the solubility of lithium hexafluorophosphate in a solution and display the test results on a display screen, making it convenient for operators to read and analyze the data. In actual applications, the electronic detector 4 can be connected to a smart terminal such as a computer or mobile phone via a data cable or Bluetooth, enabling remote data transmission and real-time monitoring.

[0033] In addition, reference Figure 1-Figure 3 It can be seen that in the present application, the pull-out part includes: a pull-out rod 3, a force-bearing disc is fixed at one end of the pull-out rod 3, and a web 11 is fixed at the other end of the pull-out rod 3, the web 11 is adapted to the tube body 1, the force-bearing disc is larger than the web 11, and the notch 5 is opened at the end of the pull-out rod 3 facing the web 11.

[0034] It should be added that in the present application, a connecting tube 6 and an injection valve tube 9 are fixed to the top of the tube body 1 respectively, the connecting tube 6 and the injection valve tube 9 are both connected to the tube body 1, the connecting tube 6 and the electronic detector 4 are screwed together, and the injection valve tube 9 and the storage barrel 10 are connected.

[0035] It should be noted that in the present application, the discharge component includes: a discharge channel 13, which is installed at the middle end of the bottom of the tube body 1 and is connected to the tube body 1. The bottom of the discharge channel 13 is rotatably connected to a locking plate 7 equipped with a lock, and a filter screen 12 is installed in the middle of the discharge channel 13.

[0036] It should be further explained that in the present application, multiple connecting tubes 6 and electronic detectors 4 are provided at one end of the top of the tube body 1 away from the injection valve tube 9, the inner wall of the connecting tube 6 is provided with threads, and the electronic detector 4 is fixed with screw threads that match the threads near the detection end of the electronic detector 4.

[0037] In addition, reference Figure 1 It can be seen that in the present application, a locking cap for sealing is installed at the mouth of the storage barrel 10, and the inner wall of the storage barrel 10 is coated with a protective coating, wherein the solution dissolved in lithium hexafluorophosphate in the present application is dichloromethane, ether, DME, DMC, DEC and other solvents, and the protective coating is an acid- and alkali-resistant anti-corrosion coating, which can effectively resist the corrosion of chemical substances such as lithium hexafluorophosphate, ensuring the long-term use of the storage barrel 10.

[0038] It should be added that when the device is actually used, when the solution dissolved in lithium hexafluorophosphate is a DMC solvent, the operator first opens the mouth of the storage barrel 10 through the locking barrel cap, places the prepared lithium hexafluorophosphate crystals into the storage barrel 10, and then closes the locking barrel cap to ensure that the lithium hexafluorophosphate crystals in the barrel are isolated from the external environment to maintain their purity. Next, the operator tightly connects the liquid extraction cap 8 to the container containing the DMC solvent to ensure that the solution will not leak or be mixed with impurities during the extraction process. It should be noted that after the preparatory work is completed, the operator starts to operate the extraction rod 3. Through reciprocating motion, the extraction rod 3 extracts the DMC solvent from the container into the interior of the tube body 1. During the extraction process, the operator needs to maintain a stable force and speed to ensure the uniformity and accuracy of the solution extraction. In addition, after a certain amount of DMC solvent is extracted into the tube body 1, the operator inserts the detection end of the electronic detector 4 into the gap 5. At this time, the electronic detector 4 begins to detect the solubility of lithium hexafluorophosphate in the DMC solvent. The detection data will be displayed in real time on the display screen of the electronic detector 4 for the operator to read and analyze.

[0039] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
