An air-releasing valve for use in a suction apparatus and a suction robot having the air-releasing valve are provided. The air-releasing valve comprises an activation unit and an air-releasing valve retaining base (3). An air-releasing hole (11) in communication with a negative pressure chamber (18) of the suction apparatus is provided on the air-releasing valve retaining base (3). The activation unit is provided on the air-releasing valve retaining base (3) and is movable relative to the air-releasing valve retaining base (3) to open the air-releasing hole (11). A switch (4) is provided on the air-releasing valve retaining base (3). The activation unit opens the air-releasing hole (11) and triggers the switch (4) to shut off a vacuuming apparatus (14) of the suction apparatus simultaneously. The air-releasing valve is capable of rapidly releasing air from the suction apparatus and shutting off the vacuuming apparatus (14) in a timely manner.
