Description

Technical Field

[0001] The utility model relates to the technical field of cooling fans, in particular to a cooling fan used on a robot dog. Background Art

[0002] The working principle of the cooling fan is realized by energy conversion, that is: electrical energy → electromagnetic energy → mechanical energy → kinetic energy. Cooling fans are widely used in computers, communication products, optoelectronic products, consumer electronics, automotive electronic equipment, switches, medical equipment, heaters, air conditioners, inverters, ATMs, car refrigerators, welding machines, induction cookers, audio equipment, environmental protection equipment, refrigeration equipment and other traditional or modern instruments and equipment. The cooling fan used on the robot dog needs to be removed and cleaned after a period of use and the motor needs to be maintained. The fan blades are generally fixed on the output shaft of the motor. If the fan blades need to be removed, the protective cover on the cooling fan housing needs to be removed first, and then the fan blades need to be removed with tools, which is time-consuming and laborious. Therefore, a cooling fan for the robot dog is proposed to facilitate the removal of the fan blades. Utility Model Content
