Automatic spill-proof cover

Abstract

The invention provides an automatic spill-proof cover. The automatic spill-proof cover comprises a pot cover body and a baffle cover, wherein the baffle cover is connected with the pot cover body; anexhaust hole is formed in the position, corresponding to the lower part of the pot cover body, of the pot cover body; a steam storage space is formed between the baffle cover and the pot cover body; and during use, the baffle cover can be deformed after being impacted by the pressure of steam discharged by the exhaust hole, so that a channel for connecting the steam storage space between the baffle cover and the pot cover body with the outside is expanded. The spill-proof cover covers a pot opening of the pot body, and the baffle cover covers the upper side of the exhaust hole in the early stage of heating, so that the heat preservation effect is achieved. As the temperature is increased, the pressure in a pot is gradually increased and the high-pressure steam in the pot is discharged fromthe exhaust hole to impact the baffle cover, so that the baffle cover is deformed upwards automatically by impact force of the steam, the steam storage space between the baffle cover and the pot cover body is opened, the exhaust hole becomes open, and the steam in the pot is discharged rapidly; and boiling liquid is in contact with cold air outside the pot and the temperature of the boiling liquid is no longer increased, so that the liquid is retained in the pot and the effect of automatic spill prevention is achieved.

Description

technical field [0001] The invention relates to the technical field of cooking tools, in particular to an automatic spill-proof cover. Background technique [0002] Usually, when people are heating viscous liquids such as soup, porridge, and dairy products, if no one is guarding and covering the pot, the liquid in the pot will usually overflow out of the pot, and there is a danger of extinguishing the stove and causing gas leakage. . If the pot is not covered for cooking, a large amount of heat will be lost during cooking, resulting in energy waste, the cooking time will be prolonged, and the cooking food in the pot will also have the problem of uneven heating, which will affect the cooking quality of the object food. [0003] Therefore, there are some anti-spill covers on the market, but the anti-spill effect of existing anti-spill covers is general. There is an opening in the middle, and the overflowing liquid flows back into the container through the opening after being...

AI Technical Summary

Problems solved by technology

Cooking without a lid on the pot will cause a lot of heat loss during cooking, resulting in waste of energy, prolonging the cooking time, and uneven heating of the food in the pot, which will affect the cooking quality of the object food

[0003] Therefore, there are some anti-spill covers on the market, but the anti-spill effect of existing anti-spill covers is general. There is an opening in the middle, and the overflowing liquid flows back into the container through the opening after being contacted with the cold air outside to realize the anti-overflow function. However, the anti-overflow cover has a poor heat preservation effect when it is not boiling, causing energy and time loss. Waste, uneven heating of food, etc.

[0004] There is also an existing anti-overflow cover, which includes a pot cover body and a cover that are sunken from the edge to the middle. The pot cover body is provided with an exhaust port for discharging gas and boiling liquid in the pot. connection, the cover is provided with blades, and the blades are used to block the exhaust port on the pot cover body. Before use, first rotate the cover so that the blades on the cover cover are closed with the exhaust port on the pot cover body, or open the cover directly. The leaves of the cover, but the insulation effect is poor

When the food in the pot is boiling, when it is necessary to increase the exhaust space, it is necessary to manually rotate the cover to stagger the blades and the exhaust port. The exhaust port is fully open for rapid exhaust, but this will be caused by steam and Risk of scalding from boiling liquid
