Biological incubator

The utility model relates to the technical field of incubators, in particular to a biological incubator which comprises an incubator and an incubator door, the incubator door is hinged to the outer wall of one side of the incubator through a hinge, the biological incubator further comprises a circulating air cavity, the circulating air cavity is arranged on the inner wall of a shell of the incubator, a fan is arranged at the bottom of the incubator and connected with the circulating air cavity, and the incubator door is hinged to the outer wall of one side of the incubator. Materials needing to be cultured are placed at the top of the placement plate at a designated position, when the materials are not many, the materials are placed on the same placement plate, then the box door is closed, the pressure sensor at the bottom of the placement plate transmits a signal to the controller, the controller controls the electromagnetic valve at the corresponding position to be opened, and the materials are placed on th
