[0002] SPF experimental mice are mice that are called specific pathogen free. They are widely used in laboratory research to simulate human diseases, especially in the field of drug research. SPF mice are bred using multiple technologies such as bacterial filters, air filters, and artificial breeding. Their immune systems are relatively fragile and are not infected by pathogens, which can reduce experimental errors and improve experimental accuracy.

[0003] When transporting SPF experimental mice in traditional transportation cages, the mouse excrement will accumulate at the bottom of the cage, which will contaminate the SPF experimental mice. At the same time, they will be contaminated by external pathogenic microorganisms during transportation, and the cleanliness of the SPF experimental mice cannot be ensured. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model combines structures such as air holes, filter membranes, V-shaped material guide frames, filter plates, feces collection frames, drive motors, drive rollers, rubber toggle plates, batteries and control switches. During transportation, air is exchanged through two air holes, and the filter membrane is used to prevent pathogens in the cage from spreading outward or pathogens on the inside and outside of the cage from spreading inward. The filter plate can be used to place feces produced by SPF mice being transported in the V-shaped material guide frame, and then the drive motor is started by the control switch to drive the drive roller to rotate continuously at a uniform speed, thereby cooperating with the rubber toggle plate to rotate the feces and place them in the feces collection frame. Since multiple rubber toggle plates rotate, the feces collection frame can always be blocked, thereby preventing feces from accumulating in the cage during transportation and contaminating the SPF mice, thereby further ensuring the cleanliness of the SPF experimental mice being transported.

[0013] 2. The utility model combines structures such as fans and filter covers. When SPF mice are transported, the fan is started by controlling a switch, thereby speeding up the air flow in the cage, thereby improving the ventilation effect of the cage, and cooperating with the filter cover to prevent the SPF mice from touching the working fan and causing harm to the SPF mice.
