[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, before cleaning, the sampling needle is passed through the inside of the positioning frame 3. Then, the knob 20 is rotated to drive the threaded rod 18 to rotate. The rotation of the threaded rod 18 inside the threaded holes on both sides of the positioning frame 3 can push the folding tarpaulin 17 and the sliding plate 21 to move. The placement port 2 is sealed by the unfoldable and retractable folding tarpaulin 17 to prevent the cleaning fluid from splashing out.

[0029] The bottom of the cleaning chamber 1 is movably connected to a water collection tank 8, the top of the water collection tank 8 is fixedly connected to an external threaded cylinder 23, the bottom of the outside of the cleaning chamber 1 is fixedly connected to a positioning plate 25, the bottom of the positioning plate 25 is fixedly connected to a sealing ring 24, and the top of the positioning plate 25 is movably connected to a threaded cover 22.

[0035] Working Principle: In use, before cleaning, the sampling needle is inserted through the positioning frame 3. Then, rotating the knob 20 drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 within the threaded holes on both sides of the positioning frame 3 pushes the folding tarpaulin 17 and the sliding plate 21 to move. The expandable and retractable folding tarpaulin 17 seals the placement opening 2, preventing cleaning fluid from splashing out. During cleaning, cleaning water is introduced into the water guiding chamber 4 through the water guide pipe 6. The water guiding chamber 4 disperses the water to the spray nozzle 5 and sprays it out to clean the sampling needle.
