[0040] Working principle: In normal state, the movable contact 5622 is in contact with the fixed contact 542. When the first temperature sensing tube 31 or the second temperature sensing tube 32 senses the change of the external temperature, the displacement of the upper diaphragm 411 and the lower diaphragm 421 of the capsule 4 is caused by the change of the liquid expansion in the inside. When the temperature rises to the set value, the movable contact 5622 is separated from the fixed contact 542 by the porcelain column 6 pushing the spring assembly 56, so that the switch is opened. When the temperature decreases, the movable contact 5622 is in contact with the fixed contact 542 again, so that the switch is closed. Through the above process, the temperature controller is accurate in temperature control and sensitive in temperature sensing, and the temperature control function is realized.

[0041] The above only describes some embodiments of the present application, and those skilled in the art can make several modifications and improvements without departing from the concept of the present application, which are all within the protection scope of the present application.
