Abstract
The invention discloses an informationized universal electric furnace with warning and fingerprint recognition functions. The informationized universal electric furnace comprises a universal electric furnace body, a protective cover, a fingerprint recognizer, a control unit, a pin base, an electromagnet, a locking pin, a reset spring, a temperature sensor and a buzzer. After the fingerprint recognizer recognizes identity information of a user, the control unit switches on the electromagnet and a circuit in the universal electric furnace body; the electromagnet starts to be powered on, magnetic force of the electromagnet attracts the locking pin back into a pin hole, and meanwhile the locking pin gradually compresses the reset spring; when the locking pin completely enters the pin hole of the pin base, a sealing cover loses limitation of the locking pin, and then the user can operate the universal electric furnace after pushing the sealing cover horizontally. When the user rotates a knob switch, a pin shaft touches a counting switch on a counter, the counting switch records operation information and operation time of this time, the counter stores the information into a memorizer, and the memorizer transmits the information to an external upper computer. If the temperature in the universal electric furnace exceeds a set value, the buzzer will send out a warning signal.
