An intelligent temperature adjusting device based on an electric heating vessel comprises a shell, the shell is provided with an air inlet and a swing switch, a bimetallic strip is arranged in the shell and matched with one end of the swing switch, the other end of the swing switch controls connection or disconnection of conducting strips through an ejector rod, the ejector rod penetrates through the shell, and an elastic piece is arranged between the swing switch and the shell; the conducting strips comprise the first conducting strip, the second conducting strip and the connecting conducting strip, and one end of the ejector rod is matched with the swing switch; a conducting strip containing groove is manufactured in the shell, the conducting strips are placed in the conducting strip containing groove, and a seal cover is arranged outside the conducting strip containing groove. The temperature adjusting device is pushed by steam to achieve the purpose of achieving outage when water boils, after water is boiled, steam enters the temperature adjusting device through the air inlet and triggers the bimetallic strip to spring up, and the conducting strips are disconnected through the swing switch and the ejector rod to complete outage. The intelligent temperature adjusting device is simple in structure, safe to use and accurate in control.
