Pot cover capable of preventing boiling overflow

Abstract

The invention relates to the technical field of kitchen appliances, and discloses a pot cover capable of preventing boiling overflow. The pot cover comprises a pot body and a cover body; fixing framesare fixedly connected to the two sides of the inner wall of the cover body, supports are fixedly connected to the two sides of the top of the inner wall of the cover body, piezoelectric crystals arefixedly connected to the bottoms of the supports, a vibrating membrane is fixedly connected to the bottoms of the fixing frames, and the upper surface of the vibrating diaphragm is fixedly connected with a striking rod. According to the pot cover capable of preventing boiling overflow, heat waves generated in the pot body drive the vibrating diaphragm to vibrate, the vibrating diaphragm drives thestriking rod to beat the piezoelectric crystals to generate current, the piezoelectric crystals energize the electromagnet to generate magnetism, the electromagnet pushes the electric contact downwards through the magnetic characteristic, and the electric contact makes contact with the conductive point; and then the current generated on the piezoelectric crystal connected with the electric contact can be transmitted to the conductive point, and the cold air can enter the pot body through the cooperative use of the conductive point, the telescopic rod and the cover plate, so that the anti-overflow effect is achieved.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a pot cover for preventing boiling and overflowing. Background technique [0002] With the improvement of people's life, people's life is more and more inseparable from household appliances, such as household appliances such as electric rice cooker, induction cooker and electric pressure cooker. Although these appliances have brought great convenience to people's life, they are heating The problem of overflowing pots in the process has always troubled people, so an anti-spilling pot was developed according to people's needs. [0003] At present, the anti-overflow pots on the market are generally anti-overflow by installing a sounding device on the pot lid, or by installing a thermostat at the bottom of the pot to detect the temperature in the pot, but these two anti-overflow methods have more or less differences. The problem is, first of all, the method of setting the...
