According to the Lenz's law mis-unplugging prevention socket for the illumination lamp, through cooperative use of a second electromagnet and a coil, when a plug is inserted into the socket, the second electromagnet is in a power-on state, magnetism generated at the top of the second electromagnet is an S pole, and when the socket tends to be separated, the coil and the second electromagnet attract each other according to the Lenz's law. And the plug is effectively prevented from moving towards the top, so that the effect of preventing mistaken pulling is achieved.

The invention provides an overflow protection device for an induction cooker, and relates to the technical field of kitchen supplies. The overflow protection device comprises a cooker body, and a water inlet is formed in the top of the cooker body; a retaining ring is fixedly connected with the inner wall of the cooker body, and an electric contact I is fixedly connected with the inner top wall ofthe retaining ring; and water leakage holes uniformly distributed are formed in the bottom of the retaining ring. According to the overflow protection device for the induction cooker, through cooperative application of an electric contact III and an electric contact IV, and in the initial state, an electromagnet I and an electromagnet II are in a power-off state, and in case of overflow of the induction cooker, a floating block is moved upwards under the buoyancy effect of water, so that the electric contact I and an electric contact II are electrically connected; and the electromagnet I andthe electromagnet II are powered on. At the moment, the floating block is moved downwards under the magnetic attraction effect of the electromagnet I and the electromagnet II, and a conductive block is moved upwards under the effect of centrifugal force, so that the electric contact III and the electric contact IV are separated; thus, the effect of disconnecting a circuit of the induction cooker is achieved, and the circuit is effectively cut off; and the safety of the induction cooker is protected.
