Cage changing workstation

A cage changing workstation belongs to the technical field of animal experiments. Which comprises an upper shell (2) and a lower shell (6), and is characterized in that a controller is arranged in the upper shell (2), an air outlet pressure sensor is arranged at an air outlet of an upper air bellow (13), an air inlet pressure sensor is arranged at an inlet of a lower air bellow (15), and the air outlet pressure sensor and the air inlet pressure sensor are connected with the controller; a bottom frame (18) is horizontally arranged at the bottom in the lower shell (6), a lifting mechanism (17) is arranged on the surface of the bottom frame (18), and the workbench (3) and the lifting mechanism (17) are fixed. According to the cage replacing work station, the air speed sensor and the pressure sensor are arranged at the outlet of the upper air bellow and the inlet of the lower air bellow to serve as reference for replacing the filter element, and various defects that in the prior art, the filter element replacing
