With the improvement of people's living standards, household appliances are indispensable products in modern people's lives, providing a lot of convenience for people's lives. As household appliances enter thousands of households, the types of electric heating tube products used are increasing. Functionally, there are electric kettles, rice cookers, refrigerators, washing machines, electric frying pans, soybean milk machines, electric ovens, water heaters, steam boilers, steam irons, etc. Their heating methods have changed from the original firewood, coal or natural gas to electric heating. Electric heating is mainly achieved by the electric heating tube being energized to generate heat. Now, more and more electrical products are used in every household, and the environmental quality has been improved.

[0003] Currently, mainly bare electric heating wires are used for heating. The bare electric heating wires are very easy to oxidize, have a short service life, low material utilization rate, seriously waste raw materials, and have poor safety. In the 1960s abroad, research and development of electric heating tubes began. The electric heating wires were installed inside the tubes, and at the same time, insulating materials with good heat transfer and heat dissipation were installed to isolate them from the air, improving the service life of the electric heating wires and enhancing safety. In China, research and development of electric heating tubes began in the 1990s, and only gradually began to replace the bare wire heating with electric heating tubes after 2000.

[0023] A lead rod 10 is installed at the center of the insulating oxidation 8, and an insulator 11 is arranged at one end of the lead rod 10.

[0024] One end of the electric heater tube shell 9 is provided with a terminal block 17, and a sealing glue 12 is arranged at one end of the terminal block 17.

[0025] A thermostat 13 is installed inside the electric heating plate package 3, and a fuse 14 is installed at one end of the thermostat 13.

[0028] In this embodiment: When a working voltage is applied across the two ends of the electrode terminal 17 of the electric heating tube, current passes through the electrode terminal 17, the lead rod 10, and flows into the resistance wire 7. The resistance wire 7 converts electrical energy into heat energy, and the heat is transferred to the insulating magnesium oxide 8 and the aluminum tube shell. Then the heat is further transferred to the aluminum plate 5, the aluminum plate 5 transfers it to the stainless steel plate 4, and the stainless steel plate 4 transfers it to the water, so that the water in the steel plate absorbs heat and vaporizes into steam, and the steam cooks the eggs. Among them, the electrode terminal 17 and the lead rod 10 play a bridging role and are used to connect the resistance wire 7 and the external power supply; the resistance wire 7 is a key component that converts electrical energy into heat energy; the insulating magnesium oxide 8 plays an insulating role between the resistance wire 7 and the aluminum tube shell, and at the same time conducts the heat emitted by the resistance wire 7 to the aluminum tube shell; pure aluminum has a high thermal conductivity and a fast heat conduction speed. The aluminum plate 5 timely absorbs the heat released from the aluminum tube, and the aluminum plate 5 plays a role in timely dissipating the heat on the aluminum tube. At the same time, it plays a role in installing the temperature controller to prevent the water in the steam kettle from boiling dry and causing dry burning, resulting in the damage of the aluminum tube shell; the fuse 14 is installed on the aluminum plate 5. When an abnormal situation occurs in the temperature control, that is, the water in the steam kettle boils dry and dry burning occurs, the fuse 14 disconnects at a certain temperature to prevent the aluminum tube shell from being damaged; the brazing material is used to connect the aluminum tube, the aluminum plate 5 and the stainless steel plate 4. The stainless steel plate 4 is connected to the shell of the egg cooker with a positioning block and screws, which not only plays a role in holding water but also conducts heat.
