Description

Pot mouth sealing structure and pot cover Technical Field The utility model relates to the technical field of pot sealing, in particular to a pot opening sealing structure and a pot cover. Background The fixing structure of the detachable cover plate group of the electric pressure cooker in the current market mainly comprises the following modes: 1. The detachable and washable cover plate is fixed on the pressure bearing plate fixing column through silica gel, but because the silica gel material has elasticity and deformability, under the vibration environment generated during the working of the electric pressure cooker, the silica gel fixing point is easy to loosen, so that the detachable and washable cover plate is not firmly fixed, and the structural requirement of high reliability of the electric pressure cooker cannot be met; 2. The nut fixed structure adopts a separated nut to install and fix the detachable cover plate, and the mode can provide a better fixing effect, but a user needs to use two hands simultaneously when operating, one hand fixes the detachable cover plate, and the other hand tightens or loosens the nut, so that the operation is complex, and great inconvenience is brought to the user; 3. The handle-protruding structure is characterized in that a protruding handle structure is designed on the detachable and washable cover plate, so that the handle-protruding structure is convenient for a user to hold and operate, but when the handle is provided with the silica gel sealing ring, the silica gel sealing ring cannot rotate along with the handle when the user rotates the handle due to the fact that the silica gel sealing ring has a high friction coefficient, so that a good limiting effect cannot be achieved, and the reliability of structure assembly is affected. Disclosure of utility model First, the technical problem to be solved The utility model aims to solve the technical problems of providing a pot opening sealing structure and a pot cover, solving the problems in the prior art, realizing the reliable fixing of a detachable and washable cover plate, the convenience of one-hand operation and the function of good rotation limit after being provided with a sealing ring.
