Problems solved by technology
[0004] (1) It is necessary to accurately adjust the relative position of the needle tip and the water column, and ensure that the area above the needle tip (the part immersed in the sample or reagent during sampling) is fully wrapped by the water column to ensure that it is cleaned, which increases the difficulty of coordinate adjustment;
[0005] (2) When the needle tip is rinsed with one-sided water column, the needle tip on the opposite side of the water column cannot be effectively rinsed, and the rinse effect is poor, resulting in occasional unclean cleaning;
[0006] (3) It takes a long time to flush the needle tip, the flushing efficiency is poor, the cleaning solution is wasted, and the cleaning time is long;
[0007] (4) Water column washing, the water flow is unstable, and the needle tip hangs seriously after washing

The invention discloses a cleaning structure for avoiding liquid hanging on a sampling needle, which includes an upper body, a middle body, a lower body, a system liquid joint, and a strengthened cleaning liquid joint. The upper body includes a first threaded hole and a small cavity hole. Both sides of the upper body are formed with the first threaded hole, the inner side of the upper body is formed with the small cavity, and two sides of the small cavity are formed symmetrically on the inner side of the upper body. As for air holes, a through hole is provided at the intersection of the two air holes and the small cavity. The invention can effectively avoid hanging liquid after cleaning the needle tip, has good cleaning effect, high cleaning efficiency, reduces the amount of cleaning liquid, saves time and labor, and has high working efficiency.
Description
technical field [0001] The invention relates to the technical field of cleaning structures, in particular to a cleaning structure for avoiding liquid hanging on sampling needles. Background technique [0002] In the automatic chemiluminescence immunoassay analyzer, after the reagent needle and the sample needle are added, in order to avoid the interaction between different samples and reagents, when collecting the next sample or adding the next reagent, it is necessary to adjust the sample needle. Cleaning, whether the cleaning is clean or not directly affects the experimental results. [0003] At present, the sample needle or reagent needle is often cleaned by water column flushing, and the cleaning method of flushing the needle tip by water column has the following defects: [0004] (1) It is necessary to accurately adjust the relative position of the needle tip and the water column, and ensure that the area above the needle tip (the part immersed in the sample or reagent...
