Abstract: A blower includes an adjusting device connected to the air outlet of the case unit and the adjusting device includes a fixed plate, a rotatable plate which is rotatably connected to the fixed plate. The fixed plate includes two first apertures and the rotatable plate includes two second apertures. The rotatable plate is rotated to adjust a size of communication of the first and second apertures so as to control the volume of air that is sucked into the blower.

Abstract: A blower includes a base having a transverse passage for receiving a motor therein and a fan device driven by the motor extends from a hole in an end of the base. A casing including an outlet is connected to the base and mounted to the fan device. An anti-back device is engaged in the outlet and includes a frame to which a plate is pivotably connected. The plate is opened by the air sent via the fan device in one direction and seals the outlet when air goes in opposite direction.

Abstract: A rotating inflatable device includes a base having an outlet a top thereof and an inlet in a side of the base. A blower is received in the base and driven by a motor. A drive part is received in the base and includes a rotating rod which is driven by another motor via a speed reduction unit. A drum to which a lower opening is mounted includes an annular ring and a central part which is located at a center of the drum by a plurality of ribs connected between the annular ring and the central part. A top end of the rotating rod is co-axially connected to the central part. A central shaft composed of a plurality of sections has its a lower end connected to the central part. A top end of the central shaft extends through a top opening of the balloon and is connected to a plate which seals on the top opening of the balloon.

Abstract: A blower includes a casing for receiving a motor therein and the shaft of the motor extends through an opening in a top surface of the casing. A blade assembly is connected to the shaft and a cover is fixedly connected to the top surface of the casing and has an air outlet. The blade assembly is enclosed by the cover. Two recesses are defined in an outer periphery of the casing and a handle is connected to one of the two recesses, and an air inlet is defined in an inside of the other recess of the casing.
