Description

Technical Field

[0001] The utility model relates to the technical field of pressure cookers, in particular to a pot cover assembly and an electric pressure cooker. Background Art

[0002] Taking the current electric pressure cooker as an example, it includes a pot body and a pot cover. The top of the pot body is annularly arranged with concave and convex pot teeth, and the inner wall of the pot cover is provided with buckling teeth corresponding to the pot teeth. The pot cover is rotated so that the buckling teeth are under the convex pot teeth to achieve buckling connection between the pot cover and the pot body. Conversely, when the buckling teeth rotate with the pot cover to under the concave pot teeth, the pot cover can be flipped up or opened. Since it is dangerous to open the lid when the air pressure in the pot is high, existing pressure cookers are all equipped with a self-locking mechanism, which includes an air float valve that floats up and down as the air pressure in the pot changes, and a lock pin assembly that is laterally slidably arranged in the pot lid, one end of the lock pin assembly is attached to the surface of the pot teeth of the pot body, and the other end of the lock pin assembly extends to the air float valve. Under normal circumstances, if the air pressure in the pot is lower than the safe lid opening pressure, the air float valve will not block the lock pin assembly. When the pot lid is rotated to open, the lock pin assembly moves freely along the pot teeth surface and does not affect the lid opening; on the contrary, when the air pressure in the pot is too high, the air float valve blocks the lock pin assembly so that the lock pin assembly cannot move freely along the pot teeth surface of the pot body, so the pot lid cannot rotate. Of course, the above is only a theoretical state, but this structure actually still has certain safety hazards, because there must be a certain virtual position between the air float valve and the lock pin assembly (if there is no virtual position, the air float valve will be stuck). Even if the air pressure in the pot is high, if the rotational force acting on the pot lid to open the lid is large, the lock pin assembly can overcome the resistance of the air float valve and change the state of the air float valve. The lid can be opened in this state that is not conducive to opening the lid, which brings huge safety hazards. Therefore, it is necessary to improve this structure. Utility Model Content
