In scientific research in many fields, laboratory animals play a very important role in safety tests, effect tests, and standard tests.

[0003] In the field of vaccine production, using animals for experiments is one of the important methods to obtain experimental data. Important data in the vaccine development process can be obtained by observing experimental animals after vaccination and conducting group control experiments. Usually, experimental animals need to be transferred between different areas, such as between the breeding site and the laboratory, between the laboratory and the observation room, etc. The reasonable transfer and movement of experimental animals is the basis for ensuring the normal progress of the experiment and one of the important conditions for obtaining accurate experimental conclusions. Therefore, animal transfer boxes are needed.

[0004] The existing experimental animal transfer box usually includes a box with rollers, the internal space of the box is layered by partitions, and air holes are set on the box for experimental animals to breathe. In order to isolate it from the external environment as much as possible, a filter layer is installed on the aforementioned air holes to filter the in and out airflow to a certain extent. However, in the actual working process, it is found that the experimental animal box with the above structure has the following problems: first, the filtering effect provided by the transfer box on the in and out airflow is limited, not only can it not fully prevent foreign particles in the external environment from entering the box, but it can also not prevent foreign particles in the internal environment from being discharged to the external environment, and the above transfer box does not have the function of actively delivering air, and the internal and external airflows are not smooth, which can easily lead to suffocation of experimental animals; secondly, when taking and placing the above experimental animals, the staff needs to put their arms deep into the box to grab the experimental animals, which is inconvenient to operate and easy to cause strain; thirdly, there is air circulation between the spaces used to place different animals, which can easily affect the subsequent experimental operations on the animals and the acquisition of experimental conclusions. Therefore, it is urgent to design an animal activity transfer box to solve the above problems. Utility Model Content
