The invention relates to an automatic air exhaust valve. At present, no dredgers on the market is provided with an automatic air exhaust valve, as a result, air in the dredgers cannot be exhausted out, and sewage cannot enter the dredgers; and when dredging squeezing work is done, air is squeezed out. A dredger with the automatic air exhaust valve is placed into a blocked toilet bowl, air in the dredger ejects a control ball shown in the drawing 3 under the pressure of water and is exhausted through the automatic air exhaust, and water enters the dredgers. When dredging squeezing work is done, the control ball moves upwards to seal an exhaust port shown in the drawing 2 under the large pressure of water, wherein the exhaust port (a hole with the diameter being 3.5 mm) shown in drawing 2 is sealed in an abutting-against manner; and in this way, an exhaust channel is closed through the automatic air exhaust valve, and it is guaranteed that water is completely squeezed to a blockage site to participate in dredging. The density of water is 733 times that of air, so that efficiency is improved by 733 times. The drawing 1 is represented by a. The drawing 2 is represented by b. The drawing 3 is represented by c. The drawing 4 is represented by d. The a, the b, the c and the d are assembled into the automatic air exhaust valve.
