Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a temperature-controlled fan. Background Art

[0002] A temperature-controlled fan is a fan with temperature sensing and regulation functions. Its working principle mainly relies on the thermistor on the fan to sense the temperature changes of the surrounding air. When the temperature rises, the thermistor will induce the wires, causing the fan to speed up, thereby increasing the air volume. On the contrary, when the temperature is lower, the fan will run at a slower speed, reducing noise and saving energy.

[0003] After long-term use, the existing temperature-controlled fans will have too many impurities on the fan blades. When the fan blades need to be cleaned, the screws on the shell need to be loosened and the shell needs to be disassembled before the fan blades can be cleaned. This makes the fan blade cleaning process very troublesome and the cleaning efficiency is low. Utility Model Content
