Zusammenfassung:	A slat for backflow prevention, a backflow prevention apparatus, and an electronic device. The slat comprises a main component(1) and a rotation shaft (2). The rotation shaft (2) is connected onto the main component (1), and divides the main component (1) into a first sub-slat (11) and a second sub-slat (12) in the lengthwise direction of the main component (1). The main component (1)is rotatable about the rotation shaft (2), and a region of the center of gravity thereof is located on the rotation shaft (2). The difference between the magnitude of a gravitational torque of the first sub-slat (11) and the magnitude of a gravitational torque of the second sub-slat (12) does not exceed a preset value.
