Abstract
A blower is provided, which comprises a housing, a blowpipe coupled to the housing, a motor located within the housing, and blades driven by the motor to generate air flow. The blower also comprises a motion sensor. The motion sensor is adapted to control the operation of the motor in response to changes in position or angle of the blower. The motion sensor can determine the angle between the blower and the horizontal plane, thereby intelligently determining whether the user wants to carry the blower by hand and wants to perform air blowing, and controls the operation of the motor accordingly.
