The invention provides a protective energy-saving hood of a pressure
cooker.The protective energy-saving hood of the pressure
cooker comprises a housing 2 arranged on a
cooker cover 1 in a sleeving mode and composed of shells 3 and side encircling sleeves 4; the shells 3 and the side encircling sleeves 4 are both made from
plastic cement; the side encircling sleeves 4 are closely matched with the shells 3 and sealed to the cooker cover 1; each shell 3 is provided with a clearance groove 22, a valve position hole 21 and other clearance hole grooves, and the lower end faces of the clearance hole grooves are sealed to the surface of the cooker cover 1; a
closed cavity 23 is defined by the housing 2 and the cooker cover 1; the
peripheral edge of the upper end of each valve position hole 21 is not higher than the lower edge of a cap hole 12; the inner side wall of each shell 3 is provided with a liner 5 made from foaming
plastic cement.The protective energy-saving hood is used on the pressure cooker cover in a matched mode and has the safety protection effect and the energy-saving and heat-preserving effects, cooking of the pressure cooker can be made convenient, and the protective energy-saving hood facilitates
energy conservation and emission reduction, so that the protective energy-saving hood has application and popularization value.
