[0002] In biomedical research, mice are commonly used as experimental animal models and are widely used in drug screening, disease mechanism exploration, treatment effect evaluation and other fields. Drug feeding is a key link in these experiments, and its accuracy and consistency directly affect the scientificity and reliability of experimental results.

[0003] The environment where mice are kept is prone to the accumulation of food residues, feces, urine and other dirt, which not only produces odors, but also breeds bacteria, viruses and other pathogens, posing a threat to the health of mice. Regular cleaning can effectively reduce the accumulation of these dirt and keep the environment clean and hygienic. A good environment helps the growth and development of mice and improves their quality of life and welfare.

[0004] Mice need to be cleaned regularly in the breeding environment to keep it clean and dry. When there are too many mice in the control group, the breeding equipment needs to be manually dismantled to disinfect and clean the inside, which will seriously increase the labor intensity of the researchers. Manual cleaning is easy to increase the stress of the mice, and the mice need to be moved as needed during cleaning, which can easily further increase the stress of the mice, produce stress reactions, and create additional variables in the data.

[0005] Therefore, there is an urgent need for a quantitative drug feeding device for mouse experiments, which can reduce the labor intensity of researchers while performing quantitative drug feeding, facilitate cleaning of the mouse breeding environment, thereby reducing mouse stress and improving the accuracy of comparative data.

[0029] (1) The present invention utilizes a mechanized driven disinfection mechanism to perform automated intermittent cleaning inside the bottom plate, and cooperates with the disinfection component to press against the bottom plate. While disinfecting the bottom plate, it can also clean the residual urine and the like on the bottom plate. In addition, due to the movable design of the shell, the pressure on the mice can be reduced, and the additional influencing factors of the quantitative feeding of the mice can be reduced, thereby ensuring the comparative effect of drug detection.

[0030] (ii) The present invention utilizes the linkage between the disinfection mechanism and the replacement mechanism to perform automated cleaning and disinfection.
