Description

Sealing ring structure, cover body assembly and cooking utensil

Technical Field

The utility model relates to the technical field of small household appliances, in particular to a sealing ring structure, a cover body assembly and a cooking utensil.

Background

In the related art, the pressure cooker generally decompresses after cooking is completed, so that the pressure in the cooking cavity is reduced to the atmospheric pressure. However, because the sealing lip is pressed on the pot opening in the cooking process, even after pressure relief, the sealing lip still keeps in a state of being completely attached to the pot opening, and when a user performs a cover opening operation, the inner pot can be taken out together with the cover body under the action of the sealing ring, namely, a pot sucking phenomenon occurs.

At present, in order to solve the above-mentioned problems, a general treatment method is to perform sun-print treatment on the sealing surface of the sealing ring, however, after the sun-print treatment, the pot body is still easily adsorbed on the cover body, that is, the anti-sucking pot with the above-mentioned operation has poor effect.
