Electric kettle with automatic power-off function available in case of gap in kettle lid

Abstract

The invention discloses an electric kettle with an automatic power-off function which is available in the case of a gap in the kettle lid. According to the kettle, an electromagnet is electrified since a temperature difference power generation device is used for absorbing heat generated when the electric kettle is used for heating water and generating electric energy on the basis of temperature difference from the outside, so that an iron sheet corresponding to the electromagnet is picked up to drive a moving block to pull an elastic reset part to descend, while a rack outside the moving block is clamped with a toothed chain; a toothed chain is arranged on a first rotating shaft and a second rotating shaft, and rotates to drive the first and second rotating shafts to rotate, rotation of the first rotating shaft enables a rotary press rod connected with the first rotating shaft to rotate and press down, the press part of the rotary press rod extends into the groove of the kettle lid to press the kettle lid, and the kettle lid is pressed down and closed, the cattle lid can be automatically closed when water is heated, various risks as the automatic power-off function cannot be started due to reduced impact of vapor for a power-off switch when vapor in the kettle body escapes from the gap since a user does not completely close the kettle lid can be prevented.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an electric kettle with an automatic power-off function that can still be used when there is a gap in the 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 characteristics of the kettle; the appearance of the electric kettle not only solves the time-consuming and laborious process of boiling water. The most important thing is that people's healthy drinking water life has a more comprehensive guarantee through the selection of cutting-edge scientific research technology and internal precision parts. Especially in the research and development of thermostats, electric kettles are constantly innovating, which directly facilitates people's lives. [0003] Electric kettles on the market today generally have such a "tripl...

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
