The invention discloses a misplaced gravity spraying device of an elevator shaft. The device comprises spraying devices and a vertical feeding pipe, wherein the spraying devices are sequentially and oppositely arranged at the two sides of the inner wall of the elevator shaft from the reciprocal fourth floor of the elevator shaft down, and the height difference of the two spraying devices is half of the height of single floor in the elevator shaft; the water outlet end of the vertical feeding pipe is connected with the spraying device, the water inlet end of the vertical feeding pipe is connected with water supply pipes of the three floors above a floor where the spraying devices connected with the vertical feeding pipe is, and automatic spraying can be realized because a current pressure difference between the water inlet end and the water outlet end of the vertical feeding pipe; a water outlet path of the spraying device is that the upper spraying device is used for outputting water to the next spraying device to form an inclined Z-shaped spraying water curtain so as to isolate high temperature smoke in the elevator shaft when a fire occurs, therefore the effect of cooling the poisonous smoke can be realized.
