摘要： Embodiments of the disclosure are directed to a back-mounted power tool system. The power tool system includes a battery package that can be used on other power tool systems, a backpack apparatus, a power tool, and a connecting member. The backpack apparatus includes a backpack harness to mount the backpack apparatus onto a user's body and a first connector to removably couple the battery package to the backpack apparatus. The power tool includes a motor driven by a power supply from the battery package. The connecting member transfers a weight of the power tool and/or a force received from the power tool to the backpack apparatus by rotatably coupling the power tool to the backpack apparatus. The connecting member further enables the power tool to rotate about a first rotation axis or a second rotation axis, the first rotation axis being perpendicular to the second rotation axis.

摘要： A handheld blower includes a housing, the housing including an air inlet and a duct assembly, the duct assembly including a duct, a motor and a fan mounted in the duct, a battery, a handle, and a blowpipe which defines a central axis. Along the direction of the central axis, the area of the flowing cross-section of an air passage at the rear end of the fan adjacent to the air inlet is larger than that of the flowing cross-section of an air outlet of the blowpipe, and the rate between the area of the flow cross-section of the air outlet of the blowpipe and the area of the flow cross-section of the flow-through area at the position of the fan is greater than or equal to 0.8.

摘要： 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.

摘要： A blower includes a fan for generating an air flow, a motor for driving the fan to rotate about a central axis, a battery pack for supplying power to the motor, an air duct portion including an air duct, the air duct extending long the central axis, a coupling portion for coupling with the battery pack, and a connection portion for connecting the air duct portion with the coupling portion. The fan is received in the air duct. The air duct includes an air duct inlet and an air duct outlet which are respectively located at the two ends of the air duct. The air duct inlet is located between the air duct outlet and the coupling portion. The connection portion is provided with an air intake space located between the air duct inlet and the coupling portion. The air intake space is opened in a radial direction of the central axis.
