Description

Residual liquid adsorption device of water quality tester Technical Field The utility model relates to the technical field of cleaning of water quality measuring instruments, in particular to a residual liquid adsorption device of a water quality measuring instrument. Background A water quality meter is an instrument for detecting and analyzing various parameters in a water sample to ensure that the water quality meets specific standards or requirements. It is capable of measuring a variety of water quality metrics including, but not limited to, pH, dissolved oxygen, turbidity, conductivity, total Dissolved Solids (TDS), residual chlorine, hardness, ammonia nitrogen, nitrate, phosphate, etc. Water quality measuring instruments can be divided into two types, namely laboratory use and field portability, according to different application fields and detection requirements. Laboratory water quality meters generally have high accuracy and stability, enabling complex analysis and long-term monitoring. The portable water quality tester is convenient to carry, can rapidly carry out water quality testing on site, and is suitable for occasions such as site emergency testing, field operation, environmental monitoring and the like. The method of use of a water quality meter generally includes the steps of sampling, calibrating, measuring, and analyzing data. Some advanced water quality measuring instruments are equipped with automatic calibration and data recording functions, which can provide real-time monitoring and long-term data recording, and facilitate trend analysis and decision support for users. The water quality tester does have the problem that liquid remains on the inner wall after being used in practical application, and after different water samples are detected, if the water samples are not thoroughly cleaned, residual sample components can be mixed into the next water sample, so that the detection result is deviated. For example, the last water sample contains a higher concentration of certain metal ions, which may remain in the detection cell of the instrument, and at the next detection, these residual ions may be erroneously counted into the detection result of the new water sample, so that the detection value of the metal ions in the new water sample is higher. Also, if the residue is capable of chemically reacting with the detection reagent, the reagent may be consumed, changing the stoichiometry of the reaction, so that the detected substance content does not correspond to the actual value. Some residual liquid is relatively stubborn and is difficult to wash cleanly by conventional cleaning liquid. These residues may adhere to the inner walls of the instrument, not only affecting the accuracy of the detection, but also possibly causing damage to the performance of the instrument. For example, the optical components of the instrument, if covered by dust or dirt, can affect the light transmittance and sensitivity of detection. For an instrument for detecting by using a chemical reagent, if the surface of the instrument has residual reagent or other substances which are not cleaned, the concentration or the reaction environment of the reagent may be changed, so that the reaction degree of the reagent and a water sample is inconsistent during each detection, and the repeatability and the reproducibility of the detection result are further affected.
