The protective cover 3 is a rectangular shell structure, and one end of the protective cover 3 is movably connected with the shell of the universal electric furnace 1 through a rotating shaft. 1 shell conflicts, and the protective cover 3 completely closes the knob switch 2 of the universal electric furnace 1 when it is in the closed state, and the positioning and locking groove on the other end of the protective cover 3 corresponds to the installation groove of the pin seat 6 on the shell of the universal electric furnace 1 , the bottom of the mounting groove is installed with a micro-stepping motor 7, a lead screw 8 and a locking block 5 in sequence. When the micro-stepping motor 7 is not powered on, the head of the locking block 5 is located outside the mounting groove and is in contact with the protective cover. The positioning locking groove on 3 cooperates to lock the protective cover 3 on the shell of the universal electric furnace 1; the micro stepping motor 7 is connected with the circuit inside the universal electric furnace 1 through the control unit; the face recognition device 4 is fixedly installed on the universal electric furnace 1 shell; On the outer wall of the electric furnace 1, the face recognition device 4 recognizes the identity information of the user and transmits the instruction information to the control unit, and the control unit controls the on-off of the micro stepper motor 7 and the internal circuit of the universal electric furnace 1.

The rotating shaft of the rotary switch 2 (that is, the rotating shaft 10 of the rotary switch) has a zigzag groove along the cross section of the rotating shaft that changes with the rotation angle of the rotating shaft. In the direction of rotation, it is in contact with the outer peripheral surface of the rotating shaft, and the depth of the meandering groove changes along the radial direction of the rotating shaft; the width of the meandering groove is consistent with the diameter of the pin shaft 11 .

The rotary switch 2 is rotatably matched with the shell of the universal electric furnace 1, the pin shaft 11 passes through the through hole on the shell of the universal electric furnace 1 and cooperates with the zigzag groove on the rotating shaft of the rotary switch 2, and the pin shaft 11 enters the zigzag groove at one end of the zigzag groove. The end face is in conflict with the bottom surface of the zigzag groove, and the end face at the other end of the pin shaft 11 is in conflict with the counting switch of the counter 12 (as shown in Figures 4 and 5); On the surface, the counter 12 is connected to the memory 13, the information of the counter 12 is stored in the memory 13 in real time, and the memory 13 sends the stored information to an external host computer in real time.

Working principle: Before using the universal electric stove, the user faces the camera of the facial recognition device. The camera captures the user's facial information and then recognizes it. After the face recognition device recognizes the user's identity information, it will start micro-stepping The instructions of the motor 7 are sent to the control unit, and the control unit controls the forward rotation of the micro stepping motor 7.
