Electric kettle capable of automatically closing kettle cover

Abstract

The invention discloses an electric kettle capable of automatically closing a kettle cover. According to the electric kettle, a temperature differential power generation device is used for absorbing certain electric energy generated due to the difference between heat generated during boiling water with the electric kettle and an external temperature, thereby causing an electromagnet to be electrified; after the electromagnet is electrified, a metal plate which corresponds to the electromagnet is attracted, so that a rotary lower pressing rod rotates, thereby causing the pressing part of the top of the rotary lower pressing rod to be pressed into a groove in the kettle cover, further causing the kettle cover to be pressed down and closed, ensuring the kettle cover to automatically close during water boiling, and preventing the reduction of impact force of water vapor on a power cutoff switch caused by escaping of water vapor in a kettle body due to a gap resulting from incomplete closing of the kettle cover by a user from causing unsuccessful starting of an automatic power failure function which causes various dangers.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an electric kettle capable of automatically closing a lid. Background technique [0002] The electric kettle was born in Chicago, USA in 1891. With the development of science and technology, fast, safe, convenient, and full use of energy have gradually become the main features of the kettle; Anxiety, the most important thing is that through the cutting-edge scientific research technology and the selection of internal precision parts, people's healthy drinking water life has a more comprehensive guarantee. Especially in the research and development of thermostats for electric kettles, new ones are constantly being introduced, which directly facilitates people's lives. [0003] Electric kettles sold on the market today generally have such a "triple protection" logo: 1. Steam induction protection, when the water boils, the steam switch will automatically turn off, so that the ke...

Problems solved by technology

[0004] Today's electric kettles have an automatic trip function, but the lid of the electric kettle has a buckle. When the user fills the water in the electric kettle and does not close the lid with force, the lid may not be completely closed. The automatic tripping function is to deform the bimetal sheet of the steam temperature sensing element through the water vapor generated when the water boils, and use the deformation to push the power switch through the lever principle, so that the electric kettle will automatically cut off the power after the water is boiled; It is not self-resetting, so the kettle will not automatically reheat after the power is turned off; but if the lid is not completely closed, there will be a gap, and a part of the water vapor will escape from the gap, and the impact on the power-off switch will be small. In this way, the electric kettle will not be powered off, causing the electric kettle to burn all the time, which consumes a lot of electricity. Even if it is not found for a long time that it keeps boiling water, it may cause the circuit board of the electric kettle to short circuit and burn out, and even cause fire and other dangers
