Meanwhile, an external liquid level meter 13 is arranged on the outer side of the bottom of the glass cup body 1, the liquid level of the glass cup body 1 is detected, when the liquid level of the glass cup body 1 is higher than the lowest liquid level of the glass cup body 1, the external liquid level meter 13 outputs detected liquid level signals to a singlechip through inner rings of a first coupler 5 and a second coupler 6, the singlechip controls a relay 12 to work normally, an electromagnetic induction coil 7 is electrified with a power supply, and an electromagnetic heating glass kettle is automatically powered off to work normally; when the liquid level of the glass cup body 1 is lower than the lowest liquid level of the glass cup body 1, the external liquid level meter 13 outputs an electric signal to the singlechip through the inner rings of the first coupler 5 and the second coupler 6, the singlechip controls the relay 12 to be disconnected, the electromagnetic induction coil 7 is disconnected from the power supply, the power supply is stopped, and the electromagnetic heating glass kettle is automatically powered off to stop working;
When the temperature sensor 4 and the external liquid level meter 13 work normally, double insurance prevents the electromagnetic heating glass kettle from dry burning; one of the two is in fault and the other works normally, so that the electromagnetic heating glass kettle can still be effectively prevented from being burned.
The magnetic conductive slurry adopted by the invention is prepared by mixing 25% of iron-nickel alloy powder, 60% of silver and 15% of glaze slurry by mass percent, the iron-nickel alloy powder and the silver powder which are more than 3000 meshes are uniformly mixed and then uniformly mixed with the glaze slurry, the surface of the high-temperature-resistant glass bead reflective paint is coated with a high-temperature-resistant heat-preservation sealing adhesive layer 5, and the high-temperature-resistant heat-preservation sealing adhesive layer 5 can be replaced by GL-1250 or other materials.
After the electromagnetic heating seat is electrified, the alternating current coil is used as a magnetic field alternating source of the electromagnetic oven, so that the glass magnetic conduction heating plate generates induction current, a plurality of eddy currents are formed in the annular magnetic conduction film, electrons are collided strongly to generate heat energy, the magnetic conduction film layer and the glass are heated simultaneously, and the heat energy is transferred into the kettle to heat liquid, so that the heat absorption area is large and the heat resistance is small; the bottom of the glass magnetic conduction heating plate is sprayed with a layer of high-temperature-resistant glass bead reflective paint, the aerogel heat insulation layer is coated outside the high-temperature-resistant glass bead reflective paint, the heat energy utilization efficiency is high, and the energy-saving effect is obvious.
The foregoing is only the embodiments of the present invention, and therefore, the patent scope of the invention is not limited thereto, and all equivalent structures or equivalent processes using the contents of the present specification and drawings are included in the scope of the invention, either directly or indirectly.
