The invention provides a cell growth inhibition experiment device for drug development, and relates to the technical field of drug development, the cell growth inhibition experiment device comprises a box body, a wiping part, an air inlet part, a cleaning part and an auxiliary part; the box body is fixed on a wall body; two fixing bases are symmetrically welded to the box body, two fixing bolts are connected to each fixing base in an inserted mode, and the four fixing bolts are all in threaded connection with expansion nuts in a wall body. The driving motor is connected with a contact switch through a wire, the contact switch is fixedly connected to the left end face of the inner wall of the box body through bolts, and the contact switch is connected with an external power source. The contact switch is aligned with the position of the stop lever, and when the door plate slides to be closed, the stop lever is in contact with the contact switch, so that power supply of the driving motor is completed, and the problems that firstly, air inlet pipelines are mostly arranged in existing devices, and dust on the pipelines needs to be manually cleaned after the devices are used for a period of time; and secondly, the problem that gas sprayed out of a middle gas inlet pipeline cannot be quickly and uniformly distributed in the box body is solved.
