[0004] The existing technology still has shortcomings:

[0005] In the above-mentioned prior art, a reaction cup cleaning mechanism is used to clean the inside of the reaction cup. However, during use, the injection needle used to clean the reaction cup sprays the cleaning liquid directly onto the bottom wall of the reaction cup, and the cleaning liquid only briefly soaks the side wall surface inside the reaction cup, and cannot effectively clean the side wall surface of the reaction cup. In the subsequent use process, the liquid remaining on the side wall surface will affect the subsequent tests. Therefore, a carrier plate cleaning device for a fully automatic biochemical analyzer is proposed. Utility Model Content

During the cleaning, the discharge needle 31 and the injection needle 32 in the reaction cup cleaning mechanism 3 are lowered, wherein multiple groups of adjacent discharge needles 31 and injection needles 32 drive the connecting plate 41 of the outer wall thereof to descend, and the last group of adjacent discharge needles 31 and injection needles 32 in the rotation direction of the carrier plate 2 drives the wiping member 33 of the outer wall thereof to descend, and the connecting plate 41 drives the sponge 42 on the bottom surface thereof to be inserted into the reaction cup 22, and the injection The needle 32 outputs the cleaning liquid, and the cleaning liquid enters the sponge 42. The sponge 42 wipes the inner wall of the reaction cup 22. After wiping, the sponge 42 absorbs the liquid in the reaction cup 22 until the bottom surface of the sponge 42 contacts the inner bottom surface of the reaction cup 22. The sponge 42 is squeezed to discharge the absorbed liquid. At this time, the drainage needle 31 extracts the liquid discharged by the sponge 42 until the liquid is completely extracted. At this time, the drainage needle 31 and the injection needle 32 rise, and the connecting plate 41 and the sponge 42 are taken out of the reaction cup 22, completing a cleaning of the reaction cup 22.
