Abstract

The invention discloses a delay cut-off valve of an electric pressure cooker, and is characterized in that a floater is connected to a temperature control piece so as to form a linkage structure moved along with the temperature control piece, after the temperature control piece generates temperature distortion, the floater is driven to move to a position of closing a steam outlet hole; the temperature control piece is located at a position of measuring the temperature of a cover or a position of measuring the temperature of the steam of a cooker body. The delay cut-off valve has the advantages that when rice is cooked to be boiled by the electric pressure cooker, the rice in the electric pressure cooker is continuously boiled until moisture is fully absorbed by the rice, and then the electric pressure cooker enters into a pressure-retaining and smoldering state, after the process, the rice grain of the boiled rice can be soft, dry, tough and chewy in a mouth and remarkable in rice flavor, no matter how much rice the electric pressure cooker cooks, the rice in the electric pressure cooker can be continuously boiled until the moisture is fully absorbed by the rice, and then the electric pressure cooker enters into the pressure-retaining and smoldering state. The delay cut-off valve has the advantages of reasonable structure, simple production and installation and low cost, and is suitable for mass production.
