Abstract

The invention relates to an intelligent electric kettle which comprises a power line. The power line connected with an alternating current power source is connected with a step-down circuit, the step-down circuit is connected with a single chip microcomputer, the single chip microcomputer is connected with a heating device through a triode and a relay, the single chip microcomputer is connected with a temperature sensor arranged on the electric kettle, the single chip microcomputer is further connected with an indicator lamp, and a switch is arranged between the alternating current power source and the heating device. The intelligent electric kettle has the advantages that the circuit is set according to the water boiling duration time, and the water boiling duration time is prolonged, so that a smaller number of toxic substances exit in the boiled water, and people can drink the healthier boiled tap water.

Description

technical field [0001] The invention relates to the field of electric kettles, in particular to an intelligent electric kettle. Background technique [0002] Scientists have confirmed that tap water contains 13 chlorides such as halides and chloroform that are potentially carcinogenic, teratogenic and mutagenic to humans. The content of such toxic substances is closely related to the water temperature: at 90 degrees Celsius, the content of halogenated hydrocarbons will rise from 53 micrograms per liter at normal temperature to 191 micrograms, and that of chloroform will rise from 43.8 micrograms to 177 micrograms; The contents of the two dropped to 110 micrograms and 99 micrograms respectively; if they continued to boil for three minutes, they dropped to 9.2 micrograms and 8.3 micrograms respectively. At this time, the boiled water can be called drinking water that meets hygienic standards. Scientific experiments have also proved that boiling tap water for 3 minutes has th...
