This utility model relates to the field of sweeper motor technology, specifically a sweeper motor heat dissipation structure, including a motor body, a
reducer, and a heat dissipation device. The
reducer is located at the drive end of the motor body, and the heat dissipation device is located on the surface of the motor body. The heat dissipation device includes a connecting plate, which is fixedly connected to the motor body. A frame is fixedly connected to one end of the connecting plate, and an air guide sleeve is fixedly connected to the end of the frame away from the connecting plate. A
drive motor is fixedly connected to the end of the motor body near the air guide sleeve, and a
fan blade is fixedly connected to the drive end of the
drive motor. The air guide sleeve is fitted onto the
fan blade. In this utility model, replacing the cycloidal pin
reducer can improve transmission efficiency and reduce motor overload. The
drive motor drives the
fan blade to rotate, and the air guide sleeve guides the
airflow to the fins to accelerate heat exchange. At the same time, the bending rod drives the
brush to clean the dust on the fins. The spring and push rod make the
brush fit the concave and convex surfaces of the fins, which greatly improves heat dissipation efficiency and reduces the probability of motor
burnout due to overheating and overload.
