Description

Technical Field

[0001] The utility model relates to the field of pressure cookers, in particular to a pressure cooker sealing mechanism with a prolonged service life. Background Art

[0002] There are many kinds of cooking utensils on the market, such as electric pressure cookers. Generally, electric pressure cookers include a pot cover and a pot body, wherein the pot cover is provided with a sealing ring. When the pot cover is closed on the pot body, the sealing ring seals the pot mouth of the pot body. However, the common problems of pressure cookers on the market are: the pot mouth sealing ring will shrink and deform inward after being used for a period of time, which will cause the sealing between the pot mouth sealing ring and the pot mouth to decrease and cause air leakage, making it difficult to reach or maintain the rated pressure in the pot, resulting in problems such as reduced food quality, inability to cook or overflowing. The existing pot mouth sealing ring has a short service life and needs to be replaced regularly, increasing maintenance costs. Utility Model Content
