Electric kettle for preventing user from forgetting to close kettle lid

Abstract

The invention discloses an electric kettle for preventing a user from forgetting to close a kettle lid. A temperature-difference power generation device absorbs temperature difference which is generated when the electric kettle heats water, and generates electric energy to make an electromagnet electrified, the electrification of the electromagnet causes the situation that an iron plate arranged corresponding to the electromagnet is pulled in and drives a movable block to descend, a rack at the outer side of movable block is matched with a toothed chain in a clamped mode, the toothed chain is provided with a first rotation shaft and a second rotation shaft, the rotary movement of the toothed chain drives the first rotation shaft and the second rotation shaft to rotate, the rotary movement of the first rotation shaft drives a rotation compression rod to rotate to stretch into a groove in the kettle lid, a movable protruding block which is connected with the movable block is inserted in a slot in a movable column which is provided with the first rotation shaft and the second rotation, when the movable block drives the movable protruding block to descend to the bottom of the slot in the movable column, the movable column is driven to descend, and the decline of the movable column causes the situation that the rotation compression rod also descends and presses the kettle lid, so that the kettle lid is pressed down and closed. When the electric kettle heats water, it is ensured that the kettle lid can close automatically. The electric kettle avoids the problem that because vapor in the kettle escapes from gaps caused by the situation that the user does not close the kettle lid completely, the automatic power-off function cannot be started.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an electric kettle for preventing forgetting to close 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 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 th...

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
