Abstract

The utility model relates to a pressure cooker adopting the form of a lid inner-buckling sealing structure. The utility model is implemented in such a way that after an ellipse cooker cover (4) is arranged into an opening on a circular cooker body (1), the ellipse cooker cover (4) is horizontally rotated by 90 degrees, so that the ellipse cooker cover (4) is just inner-buckled in the lower side of the ellipse flanging of the opening on the circular cooker body (1). The structural form is characterized in that firstly, strength required to be overcome when the ellipse cooker cover (4) disengages with the circular cooker body (1) is substantially raised (the cooker is difficult to explode away), and secondly, the higher the pressure in the cooker is, the higher the sealing degree between the ellipse cooker cover (4) and the circular cooker body (1) sealed through a rubber sealing ring (2) is. The sealing degree between the ellipse cooker cover (4) and the circular cooker body (1) is sealing strength against air leakage in the cooker.
一种采用锅盖内扣密封结构形式的高压锅炊具,它主要是采用椭圆形锅盖(4)切入圆形锅体(1)上开口后,再水平旋转90度,使其正好内扣在圆形锅体(1)上开口的椭圆形翻边的下侧来实现的。这种结构形式的特点:其一是大幅度提高椭圆形锅盖(4)脱离圆形锅体(1)时所需要克服的力度(不易被“炸”飞);其二是锅内的压力越高,椭圆形锅盖(4)与圆形(1)锅体之间通过橡皮密封圈(2)的密封程度,即抗锅内气体泄露的密封力度也越高。
