Abstract:
A handheld blower includes a housing having an air inlet and a duct assembly mounted in front of the air inlet, the duct assembly including a duct connected with the housing, a motor and a fan mounted in the duct, a battery, and a blowpipe connected to the housing by the duct assembly, the blowpipe defining a central axis in the length direction, and a handle arranged above the housing and the battery. The handle includes a gripping portion arranged on opposite sides of a plane in which the gravity center of the blower is located, and the plane is parallel to a central axis of the blowpipe and substantially perpendicular to a working ground. The gravity center of the handheld blower is adjacent to the gripping portion which enhances the handling comfort and reduces operator fatigue during long times of operation.

Claim (Index 6):
A blower, comprising:\n a motor; an air duct portion comprising an air duct, the air duct extending along a central axis; a battery coupling portion for coupling with a battery pack, the battery pack being capable of supplying power to the motor; a connection portion located between the air duct portion and the coupling portion and comprising a handle used to handle the blower, the connection portion configured to couple the air duct portion to the battery coupling portion; and wherein the air duct comprises an air duct inlet and an air duct outlet which are respectively located at two ends of the air duct, the air duct inlet is located between the air duct outlet and the coupling portion; wherein the connection portion defines an air intake space located between the air duct inlet and the coupling portion, the connection portion includes at least one side air passage for permitting an outer air flow to be induced from the at least one side air passage into the air duct inlet of the air duct and further to the air duct outlet of the air duct portion.
