Description

Technical Field

[0001] The utility model relates to the technical field of direct current motors, in particular to a fan direct current motor with a quick winding structure. Background Art

[0002] A fan is also called an electric fan or a fan. It is an electrical appliance that uses a DC motor to drive the blades to rotate to accelerate the circulation of air. It is mainly used for cooling and circulating air. It is widely used in homes, offices, shops, hospitals, hotels and other places. In the prior art, the power cord of the DC motor of a floor fan is usually in a free state after use. When the floor fan is moved, the power cord is usually wrapped around the motor housing of the electric fan for easy handling. However, due to the structural design of the fan, it is not convenient and efficient to wrap the power cord, and the power cord cannot be fixed. This makes it easy for the power cord to loosen and fall on the ground when the floor fan is moved, making it easy for the plug of the power cord to be accidentally stepped on or the power cord to be tripped, causing the power cord to be pulled and damaged, affecting the normal operation and service life of the motor.
