The rear motor cover of the small electric fan is a key component to ensure the stable operation and safe use of the fan.
In terms of material, plastic materials with light weight and certain strength are usually selected, such as ABS plastic or polycarbonate. This kind of material not only effectively reduces the overall weight, making it more comfortable for users to wear for a long time, but also has good insulation properties, which can avoid the risk of electric shock caused by accidental contact with the motor parts, and can withstand minor collisions and scratches in daily use.
Its structural design is compact and ingenious. The rear cover is generally tightly fitted to the motor body, and is securely assembled through accurate buckle or screw connection to prevent loose and falling off during the operation of the fan. The surface is often designed with heat dissipation holes or heat dissipation grilles, with the heat dissipation requirements of the motor when working, timely discharge of heat, maintain the efficient operation of the motor, and avoid performance degradation or even damage caused by overheating. Part of the back cover is also equipped with a buffer structure, such as rubber pads or sponge strips, to absorb the subtle vibration generated by the motor operation, reduce the vibration sensation transmitted to the head, improve wearing comfort, so that users can enjoy a cool breeze at the same time, but also have a quiet and smooth experience.
