Self-reliance temperature-controllable electric heater

Abstract

The invention discloses a self-reliance temperature-controllable electric heater. The self-reliance temperature-controllable electric heater comprises a substrate, an electric heating tube, a plug line and a circuit control module. The circuit control module comprises an indicator lamp, a buzzer, a temperature sensor, a valve, an insulating rod, a plug wire, a resistor, an electric heating tube wire and an insulating shell. A conductive strip is arranged between the plug wire and the electric heating tube wire, one end of the conductive strip is movably connected with the plug wire, a spring is arranged between the conductive strip and the insulating shell, and the conductive strip makes contact with the plug wire and the electric heating tube wire through stretching function of the spring. The plug wire is further connected with a temperature prompt function circuit composed of the resistor, the indicator lamp and the buzzer. Because the plug wire and the electric heating tube wire are controlled to be connected and disconnected through the arrangement of the circuit control module, and meanwhile the indicator lamp and buzzer temperature prompt function is set, the self-reliance temperature-controllable electric heater has the advantages of being safe and reliable, achieving power saving and energy consumption purposes and having the automatic power cut function through temperature control and the temperature prompt function.

Description

technical field [0001] The invention relates to the technical field of electric heating, in particular to a self-operated temperature controllable fast heating device. Background technique [0002] "Heat Fast" is a commonly used electric heater in daily life. It can be used to boil water, heat milk, make coffee, etc. It is fast and convenient, and is widely used by families, individuals, and field construction units. The "heating fast" heating coil is usually made of a thinner metal tube, which is equipped with a heating wire, and then filled with insulating materials such as magnesium oxide powder, and the heating wire is packaged and fixed in the middle of the tube. , so that it is not in contact with the tube wall, and the two ends of the heating wire are respectively connected with the power line. After electrification, current flows through the heating wire, and the heating wire generates heat. If the "heater" is immersed in the liquid, the heat will be dissipated qui...

Problems solved by technology

The utility model is composed of an induction contact, a control circuit and a relay. The combination of the no-water power-off circuit and the fast-heating circuit forms a protection device for the fast-heating-no-water power-off. It does not work, and the temperature is not controlled. If it is heated to the required temperature, it will be hot and still work, which is a waste of electricity and not energy-saving and environmentally friendly.
