When the handle 305 is rotated clockwise, the baffle plates 306 shrink towards the center of the ventilation duct of the ventilation box 4, the ventilation gap decreases, and the air intake volume decreases. When the handle 305 is rotated counterclockwise, the baffle plates 306 expand towards the inner wall of the ventilation duct, the ventilation gap increases, and the air intake volume increases. Through this adjustment, the humidity inside the incubator 1 is accurately controlled, the air humidity is reduced, the risk of disease is reduced, and the accuracy of the screening result is ensured.
