Description
Technical field
The present invention relates to the daily living article technical field, particularly the kitchen product technical field specifically is a kind of finger internal pressure releaser of cooker.
Background technology
Before the history of pot can be traced back to more than 10,000 year.Along with the continuous development of science and technology, very large variation has taken place in the material of pan and shape.See that from material the ceramic pot from initial develops into pans such as copper pot, iron pan, marmite, also more exquisite on making, the new container pot that adopts thermostable transparent glass to process in addition, visible food seethes when boiling.Now the most general also is that pot is " stainless-steel pan ", " the galvanized iron pot " that just is commonly called as the most widely.From seeing in shape, mainly develop into the flat pan of current trend from original round bottom pan.
No matter yet how huge variation taken place in the material of pan and shape.Pan still comprises the pot body that is used for cooking food and covers the pot cover on the pot body.Therefore, during with the pan cooking food, a pot body that covers fully when pot cover heats when excessive; Boiling liquid overheated in the pot body will overflow through the gap between pot cover and the pot body; Not only cause food nourishment composition to run off, and kitchen range are made very dirty, clear up cumbersome; It is very irritated that people often become, and also wastes time.
The way person of being to use commonly used who addresses the above problem keeps watch on the pan next door always, before the liquid flooding in the pot body comes out pot cover is lifted away, to prevent that the liquid flooding in the pot body comes out when overheated.But the generation that this method still can't be stopped liquid flooding on the one hand fully; Because perhaps action is too slow in an unguarded moment for the user; Still can cause that the liquid flooding in the pot body comes out when overheated; Hold onto the user on the other hand, made it during food cooking, can't do other thing, wasted the time.Therefore, the use of pan is very inconvenient, makes the user feel trouble.
Therefore, a kind of device need be provided urgently, it can prevent effectively that the liquid flooding in the pot body comes out when overheated, thereby makes the use of pan become convenient, save trouble, to satisfy the requirements at the higher level of user to pan.
