In the working state of ice-proof and ice-melting, the switch 6 is turned off, so that an open circuit is formed between the aluminum wire side interface 200 and the inductive switch interface 300.
When the temperature needs to be raised, after an open circuit is formed between the aluminum wire side interface 200 and the inductive switch interface 300, the transmission current flows through the temperature sensing steel core 103, and the current flowing through the temperature sensing steel core is increased, so that the oil temperature in the temperature sensing shell 110 is raised, the volume is expanded, the sliding rod 203 and the temperature sensing tray 450 are pushed to move leftwards, and the step control plate 569 is driven to move leftwards; under the action of the right inclined side surface 747 of the control stepped plate 569, the ice melting latches 573-1 and 573-2 gradually move outwards, finally the ice melting latches 573-1 and 573-2 are pushed out of the liner lock holes 675-1 and 675-2, the locking state of the liner 563 is released, the liner 563 moves leftwards under the action of the induction side spring 570 and the short-circuit side spring 571, and after the liner moves to a certain position, the liner is in short-circuit connection with the left end short-circuit plate 566; so that the aluminum wire side interface 200 and the inductive switch interface 300 are short-circuited, the normal state latches 564-1 and 564-2 are pushed into the inner container lock holes 675-1 and 675-2 by the normal state springs 565-1 and 565-2, and the inner container 563 is locked.
When the temperature needs to be reduced, after the aluminum wire side interface 200 and the inductive switch interface 300 are short-circuited, the current flowing through the temperature sensing steel core 103 is greatly reduced, so that the oil temperature in the temperature sensing shell 110 is reduced, the volume is reduced, the sliding rod 203 and the temperature sensing tray 450 move rightwards, and the step control plate 569 is driven to move rightwards. Under the action of the left oblique side 748 of the control step plate 569, the normal latches 564-1 and 564-2 gradually move outwards, finally the normal latches 564-1 and 564-2 are pushed out of the liner locking holes 675-1 and 675-2 to release the locking state of the liner 563, under the action of the induction side spring 570 and the short-circuit side spring 571, the liner 563 moves rightwards, and after the liner moves to a certain position, the liner and the left end short-circuit plate 566 are opened; so that an open circuit is formed between the aluminum wire side interface 200 and the inductive switch interface 300, the ice melting latches 573-1 and 573-2 are pushed into the liner lock holes 675-1 and 675-2 by the ice melting springs 572-1 and 572-2, and the liner 563 is locked.
