The invention relates to a button opening-closing type interlayersandwich pressure pan comprising a pan body, pan ears, a pan cover handle and a compound pan bottom. A regulating valve and a safety valve are arranged on a cover panel of the button opening-closing type sandwich pressure pan, a set of dragged opening and closing mechanism drives a pair of moving slide blocks on the cover panel, one ends of the slide blocks are welded with pressure opening-closing rings, a cover and the pan body are banded hooped by a pair of rings, the pressure cover is closed or opened along with the opposite or reverse movement of the opening-closing rings, a button is pressed to generated dragging force so that rocking bars are scratched up and down to drive a vertical side gear, and then the vertical side gear is meshed engaged with a circular gear through racks on the other ends of the slide blocks and is driven to the slide blocks to drag the opening-closing rings. A clip sleeve is arranged on the pan body in which a one-way valve is arranged, and the air pressure in the clip sleeve is 0.3 KPa-0.5 KPa; and the air pressure in the pan is controlled to 0-1 bar by the regulating valve. The sandwich interlayer pressure pan has the advantages of stable and firm structure, good safety, high efficiency, energy saving and convenient use, has the functions of smoldering, pressure maintaining and reboiling without fire and is suitable for various pressure pan cookers.
