The invention also can filter and prevent the waste heat of hot gas from being discharged after utilization and causing pollution to the external environment. The designed heat insulation pad can isolate the heat and prevent the heat of hot gas from being transferred to the pot cover plate, causing the pot cover plate to be overheated and easily causing harm to the operator. At the same time, it will not cause a large amount of heat loss.

The designed pressure relief cylinder, pressure relief hole, spring and movable plate are installed on the pot cover plate. The hot gas generated by the electric fryer generates a pushing force on the movable plate in the pressure relief cylinder. When the pot cover plate intercepts the hot gas pressure in the electric fryer, the hot gas pushes the movable plate up and moves it to the pressure relief hole, so that the hot gas is discharged from the pressure relief hole in time to achieve the purpose of pressure relief, avoiding the explosion caused by excessive air pressure, making the collection and utilization of waste heat and waste gas by the invention safer and more reliable. The designed support column and support cylinder can straighten and correct the spring to avoid skew and loss of elastic effect on the movable plate. BRIEF DESCRIPTION OF THE DRAWINGS
