[0002] With the continuous development of biomedical research, the use of experimental animals is becoming more and more widespread. Rodents represented by experimental mice have become one of the most commonly used model organisms due to their easy breeding, low cost, and clear genetic background. In order to ensure the scientificity and accuracy of the experiment, the living environment of the experimental animals needs to be kept highly clean.
[0003] Currently, there are mainly the following methods for cleaning the experimental mouse feeding cage: ① manual cleaning: using a cloth or brush to scrub the surface of the cage one by one by the staff, although it can be more detailed to complete the cleaning work, but it is time-consuming, labor-intensive, and easy to miss hidden parts. ② Spray disinfection: using a high-pressure spray gun to evenly spray disinfectant on the cage, which can quickly kill bacteria, but due to the presence of a lot of water vapor, it is easy to breed new microorganisms, and it is not suitable for frequent use. ③ Automatic cleaning machine: using an automatic device to wash the cage, although it improves the cleaning efficiency, but the loud noise generated by the machine running will cause the experimental mice to be startled, affecting their behavior performance.
[0004] The above methods can meet the cleaning needs of the experimental mouse feeding environment to some extent, but also have many shortcomings. Manual cleaning and spray disinfection cannot achieve high-efficiency operation, while the automatic cleaning machine improves the cleaning efficiency, but because of the high noise problem, it brings unnecessary pressure to the experimental animals, which is not conducive to maintaining a stable physiological state, and may also interfere with the researchers to carry out fine operations.
