Description

Lid and cooking apparatus

Technical field

The utility model relates to kitchen utensils fields, more specifically, are related to a kind of lid and the culinary art including the lid Utensil.

Background technique

Existing cooking apparatus such as pressure cooker, interior pot inner pressure reduction after, due to sealing ring occur at high temperature it is swollen Swollen, sealing ring is fitted closely with interior pot side wall.Being bonded between sealing ring and interior pot is tighter, and frictional force between the two is also got over Greatly.After interior pot inner pressure reduces, since sealing ring is still within swelling state, the frictional force between sealing ring and interior pot makes Cover board cannot quickly be fallen, and lock buckle teeth cannot be unclamped with pot body buckle teeth, cause lock to be unable to ease rotation, to can not achieve The Rapid opening of pressure cooker.

Utility model content

The utility model aims to solve at least one of the technical problems existing in the prior art.

For this purpose, the one aspect of the utility model is designed to provide a kind of lid.

The other side of the utility model is designed to provide a kind of cooking apparatus including above-mentioned lid.

To achieve the above object, the embodiment of the one aspect of the utility model provides a kind of lid, comprising: inner cover； Lock, be rotatably arranged in it is described it is interior cover, for making the lid be interlocked with the pot body or mutually separating；Cover board group Part is arranged in the inside of the inner cover and can move towards the inner cover, and the cover plate assembly is able to drive the lock court The inner cover movement, the cover plate assembly includes cover board and sealing ring, and the sealing ring is connected on the cover board；And elasticity Part is supported between the cover plate assembly and the inner cover, and when cover plate assembly is moved towards inner cover elastic component It is compressed.

The utility model lid provided by the above embodiment, lock connection in inner cover, and can be rotated relative to inner cover, So that lid locks together or unclamps with pot body, specifically, when lock turns to the position that lock buckle teeth and pot body buckle teeth are interlocked When, lid and pot body realization are sealed, and when lock, which turns to lock buckle teeth, mutually to be separated with pot body buckle teeth, lid and pot body are unclamped.

Pot in pressure rise when, the cover plate assembly including cover board and sealing ring is jacked up by air pressure in pot so that cover Board group part is moved towards inner cover, and is driven to latch and be moved towards inner cover, and lock buckle teeth and pot body buckle teeth fasten closely, is latched relative to interior Lid is unable to ease rotation, meanwhile, when cover plate assembly is moved towards inner cover, cover plate assembly drives elastic component that elastic deformation occurs, specifically Elastic component compressed, thus elastic component to cover plate assembly exist the elastic force opposite with the direction of motion of cover plate assembly towards inner cover, When pressure reduction to preset pressure in pot, cover plate assembly is applied to the elastic force on cover plate assembly in self gravity and elastic component Active force under move to far from the direction of inner cover, while lock being driven to move to the direction far from inner cover, so that the button latched It is unclamped due to there are gap between tooth and the buckle teeth of pot body, so that lock can be relative to inner cover ease rotation, and then realizes pressure The Rapid opening of power pot.

In addition, the utility model lid provided by the above embodiment also has following additional technical feature:
