Pressure control device of micro-pressure electric cooker and micro-pressure electric cooker

The invention relates to the technical field of electric cookers, in particular to a pressure control device of a micro-pressure electric cooker and the micro-pressure electric cooker. The pressure control device comprises an electromagnetic valve and an ejecting piece controlled by the electromagnetic valve, and further comprises a pressure control assembly. The pressure control assembly comprises a movable steel ball and a steel ball supporting base arranged on a cooker cover and used for supporting the steel ball. An exhaust hole is formed in the top of the steel ball supporting base. A concave site downwards indented, matched with the steel ball and used for placing the steel ball is arranged on the top end face of the steel ball supporting base. The exhaust hole is arranged at the bottom of a concave surface and communicated with the interior of a cooker body. A stop piece is arranged on the cooker cover. A gap for the steel ball to move is formed between the stop piece and the steel ball supporting base. When the electromagnetic valve is in a turned-off state, the ejecting piece ejects the steel ball so that the steel ball can be disengaged from the exhaust hole to abut against the stop piece. By arranging the pressure control device on the cooker cover of the electric cooker, the pressure in the cooker body can be effectively controlled, the electric cooker is convenientto uncover after cooking rice, there is no need to wait for the natural cooling of the cooker body, and waiting time is shortened.
