The invention relates to a cooking utensil and a cover. The cover comprises an upper cover, a thermal insulation cover board, as well as a driving assembly, a clamping mechanism and a detecting assembly, wherein the thermal insulation cover board is detachably arranged on one side, facing an inner pot in a pot body, of the upper cover; the driving assembly, the clamping mechanism and the detectingassembly are arranged on the upper cover; under the effect of the driving assembly, the clamping mechanism is switched between the cover closing position clamping the inner pot and the thermal insulation cover board and the cover opening position allowing the inner pot and the thermal insulation cover board to be separated; and the detecting assembly is used for detecting that whether the clamping mechanism is in the cover closing position and the cover opening position or not, and the driving assembly is controlled to stop movements when the clamping mechanism is at the cover closing position and the cover opening position. When the clamping mechanism realizes in-place cover closing or in-place cover opening, the driving assembly stops working and no longer drives the clamping mechanismto move, and therefore, the phenomenon that when no movement space is available, the driving assembly forcibly drives the clamping mechanism to move, consequently, the clamping mechanism is damaged isavoided. Meanwhile, the detecting assembly can detect that whether the clamping mechanism realizes in-place cover closing or in-place cover opening, so that the problem that the cover opening and closing are not in place is avoided.
