Abstract: A blower, including: a motor; a tubular wind wheel, a mounting plate and a connection part. The tubular wind wheel includes a plurality of blades and a plurality of connection rings. The plurality of blades is connected to each other to form an elongated hollow body. The connection part is disposed in the elongated hollow body. The mounting plate is disposed outside one end of the tubular wind wheel. The motor is disposed on the mounting plate. At least a part of the motor extends into the elongated hollow body to connect to the connection part.

Abstract: An external rotor motor, including: a rotary shaft; a plastic-packaged stator including a sleeve base, a stator core, a terminal insulator, coil windings, and a plastic-packaged body; and an external rotor sleeving on the plastic-packaged stator. The terminal insulator is disposed on the end face of the stator core. The coil windings are coiled on the terminal insulator. The sleeve base is disposed in an axle hole in the center of the stator core. The rotary shaft is disposed in the sleeve base. Two ends of the rotary shaft are supported by the bearing. One end of the rotary shaft protrudes out from the sleeve base and is connected to the external rotor. The top of the sleeve base extends outwards to form a plurality of arms, and the plurality of arms each includes an outer end which is provided with a bolt.
