Description

technical field [0001] The invention relates to the field of cooking utensils, in particular to a button-type pressure cooker. Background technique [0002] The working principle of the pressure cooker is to increase the boiling of the water in the pot by pressurizing the inside of the pot, thereby forming a higher temperature in the pot and cooking food faster and more efficiently. In a traditional pressure cooker, the lid and the body of the pot are buckled together by the interlocking flanging to realize the sealing of the body of the pot. Due to the large contact area between the flanges, it is laborious to turn the lid to open and close, and because the flanges are designed with a specific opening and closing angle, it is difficult to align them, which will lead to potential safety hazards. Chinese patent document CN201153855Y disclosed a "button type opening and closing pressure cooker" on November 26, 2008, including a pot body, a pressure cover, a sealing ring, a sa...
