The analyzer 3 is used manually to continue the detection work. At the same time, the sample addition cylinder 2 moves right to the cleaning chamber 5, and descends to be inserted into the clean water in the cleaning chamber 5, and then the clean water is drawn into the cylinder and discharged, so as to clean the inside of the sample addition cylinder 2 and the sampling needle 21. After cleaning, it is moved out of the cleaning chamber 5, moved left and inserted into the disinfection chamber 4, and finally the heating tube 43 and the ultraviolet lamp 41 are automatically sensed and turned on at a time to dry and disinfect the sampling needle 21.

[0021] In this embodiment, a waste liquid tank 52 is plugged into the right end of the reagent testing table 1; and the waste liquid tank 52 is located at the lower tube opening of the infusion tube 53, and an electric valve 56 is installed on the surface of the infusion tube 53.

[0026] As a preferred embodiment, the test tube rack 11 is convenient for storing the test tube solutions involved in the detection reagents. The reagent sensor 61 corresponds to each test tube placement position on the test tube rack 11, facilitating positioning the sample addition cylinder 2 above the required test tube. The dust-proof cover plate 6 is pushed and pulled by an electric control of the push column to move the dust-proof cover plate 6 away from or into the position above the test tube, facilitating blocking external dust and impurities from falling into the test tube solution.
