Pressure relief method and device of cooking utensil, cooking utensil and storage medium

The invention provides a pressure relief method and device for a cooking utensil, the cooking utensil and a storage medium, and the method comprises the steps: obtaining the pressure of an inner pot of the cooking utensil when a rapid pressure relief function of the cooking utensil is started; judging whether the pressure of the inner pot meets a preset execution condition for entering an exhaust stage or not; if the pressure of the inner pot meets the execution condition of entering the exhaust stage, controlling the cooking utensil to stop executing the rapid pressure relief function, and timing the stop time of the rapid pressure relief function; and when the stop time reaches a preset first time threshold value, controlling the cooking utensil to exhaust according to an exhaust duty ratio corresponding to the pressure of the inner pot. The rapid pressure relief function is controlled to stop for the preset time before exhausting every time, then exhausting is conducted, under the condition that overflow i
