Description

Technical Field

[0001] The utility model relates to the technical field of heating tube equipment, in particular to a heating tube with double NTC detection holes and a rear temperature controller. Background Art

[0002] NTC means negative temperature coefficient, which generally refers to semiconductor materials or components with large negative temperature coefficient. The so-called NTC thermistor is a negative temperature coefficient thermistor. It is made of metal oxides such as manganese, cobalt, nickel and copper as the main materials and is made of ceramic technology. These metal oxide materials have semiconductor properties because they are completely similar to semiconductor materials such as germanium and silicon in terms of conductivity. When the temperature is low, the number of carrier electrons and holes in these oxide materials is small, so their resistance value is higher; as the temperature rises, the number of carriers increases, so the resistance value decreases. NTC thermistors can be widely used in temperature measurement, temperature control and temperature compensation.

[0003] Heating tubes are widely used in daily life, but current heating tubes can only simply heat water when in use, and cannot control the water temperature, which causes great inconvenience to people when using them. Therefore, those skilled in the art provide a heating tube with a double NTC detection hole and a rear temperature controller to solve the problems raised in the above background technology.
