Background

The electric kettle is mainly used for heating liquid serving as a drink, and the main purpose of heating is to perform sterilization treatment or obtain more ideal taste, usually to heat the electric kettle to boiling, and then to pour the electric kettle from the kettle body of the electric kettle to be cooled for drinking or keep the temperature in the kettle.

In addition, the electric kettle is used for cooking various food materials such as water, noodles, scented tea, medicated food, tonic food and the like in daily life. Many food materials boil for a long time, easily overflow, have the safety risk. In the heating process of the beverage, the kettle is in a relatively closed state, and liquid can be evaporated into water vapor along with the temperature rise, so that the pressure in the kettle is increased. When the electric kettle is used for heating drinks containing food materials such as tremella, ginseng, porridge and the like, the food materials are rich in surfactants such as colloid, ginsenoside or starch, so that foam is easily generated in the heating process, and if the foam cannot be timely defoamed, the foam is easily overflowed out of a kettle body, so that accidents such as scalding and short circuit of a circuit are caused.

Alternatively, as in the technical solution disclosed in CN201511017138.3, a cylindrical anti-overflow electrode is disposed on the pot lid, and the anti-overflow electrode vertically extends into the inner container for detecting an anti-overflow signal.

However, the spout of the electric kettle is generally open, steam or bubbles can be rapidly gathered towards the spout and overflow in the heating process, and the installation position of the anti-overflow electrode is close to one side of the handle, so that the formation of foam of the spout cannot be well and rapidly collected, and an anti-overflow measure can be rapidly taken. In addition, the anti-overflow electrode is generally arranged in a cylindrical shape, the bubble contact surface is small, and the detection effect is not accurate enough.

In addition, patent application No. CN201320276373.2 discloses a kettle lid of taking filter screen, and kettle lid is equipped with the filter screen towards one side of hu zui and is used for the filtration of pouring the water in-process, but this technical scheme can not realize fine anti-overflow effect, and in the heating process, if do not detect and control, the foam can increase continuously, overflows outside the kettle body, has the safety risk.

The above description is included in the technical recognition scope of the utility model, and does not necessarily constitute the prior art.
