The invention discloses an air reservoir with an automatic water drainage function, and belongs to the technical field of engineering machinery. The air reservoir with the automatic water drainage function comprises an air reservoir which is provided with an electric blow-down valve; the inner end of the electric blow-down valve is connected with a flexible rubber hose, and the free end of the flexible rubber hose is connected with a gravity ball; a pressure switch used for detecting the air pressure in the air storage cylinder is installed on the air reservoir, and a contact switch is installed in the air reservoir. The time-delay relay and the contact switch are connected in series to form a control loop; the time-delay relay, the pressure switch and the electric blow-down valve are connected in series to form an execution loop. The air reservoir can automatically discharge water so that the labor intensity is reduced, and the timeliness of water discharge can also be ensured; the pressure switch for gas circuit protection is additionally arranged to ensure that the gas pressure of the gas storage cylinder is not lower than a preset value and the brake pressure is ensured; by additionally arranging the gravity ball and the flexible rubber hose, water can still be discharged normally when the vehicle inclines or swings.
